Yesterday I had my first night at the IAC-80 telescope. Here – for the first time in my life – I have a night assistant working with me, so it is very strange that there are things I do not have to care about anymore. (Even if I like to do everything at the telescope…)
Anyway, the night did not start well, as we had a lot of clouds, and the humidity was also quite high, so after a GRB follow up observation (already through short-lived holes on the cloud layer – done by the IAC staff), we had to close everything… But the sky was really magnificent right after the sunset.
There were some orographic clouds (lenticular clouds generated by the uplift of the Teide volcano), staying at the exact same position for hours, creating wonderful photo-opportunities. (Yes, this night was a disaster for science, but a blessing for photography.) And the whole landscape was lit by the moonlight, which turns night-time pictures to day-time photographs, but with stars on the sky! (I have a time lapse movie also covering almost the whole night here.)
Unluckily the clouds stayed, then by the time the sky finally cleared up, the humidity shot well above the 80% limit… So one hour before the dawn the sky was 100% clear, but the humidity was also 100%… I have never seen such a weather situation. This is really atypical for this time of the year on Tenerife. Though I was very tired by the end of the night, I stayed till the sunrise, because I knew the lights would be perfect then for photos like the one below ;)
After finishing the internal version (ready to be sent to the co-authors) of my first paper on Wednesday evening after weeks of hard work (even on weekends) and iteration with my supervisors, I had to pack in for a full moth, as I was getting ready to leave for two observing runs and for some holidays to the Canary Islands. As always, packing took ages, so I had no sleep at all before my taxi arrived at 5 on the morning. The most difficult part was packing my racing bike to its bike box, because everything had to be placed very carefully, to avoid any possible damage during the flights. (The wheels were placed on top of the whole stuff in separate wheel-bags, but still into the bike box).
At the end (after I had to reopen the box – at which point I was swearing a bit – because I forgot to put the big pump inside…), I had 60 kg of luggage (and I even had to leave my tripod at home, because it really did not fit in anywhere): 32 kg in the bike box (as the box itself weights 12 kg, plus the bike is 8 kg, plus I put in some other stuff too to save space in my normal bag), 22 kg as normal check-in luggage, and 6 kg in my hand luggage. (And I had to pay only 75 € for the bike box, and nothing else. Luckily.) I took the Iberia flight to Madrid at 8 AM, then another from the same company to Tenerife after waiting two and a half hours at the airport. (I still love airports like this one.)
Luckily, as the original plan was only one and a half hour, and I was a bit afraid, that the bike box will not make it in time from one plane to another… A managed to get some sleep during the flights, but I was still extremely tired upon arriving to the Canaries. (And then it came to my mind that I will have to do the same endless packing three times again in the coming month… But OK, I stop complaining.) After collecting my normal luggage, I had to go down one floor to pick up my bike box, but that floor was completely deserted – with only a few lights turned on, endless baggage claim areas with no people around at all, and then, at the very end of the area, my bike box rolled out on its own, alone. With no personnel or anyone around. It was a bit scary… Then as I stepped outside, I was shocked by the 28°C air temperature, so I took off some clothes (:P) and headed to the taxi area as fast as I could. There, the taxi drivers were the ones under a slight shock, as they realized, that all this luggage was mine, and there was no other person traveling with me :D But no worries, everything fit in perfectly (with the rear seats leaned forward), and we were on our long way up to the observatory in no time. It was still early afternoon when I arrived and checked in at the Residencia of the Observatorio del Teide. (I might consider learning Spanish instead of Dutch, if I want to get a job after my PhD as a support astronomer somewhere…) I even met two Hungarians, which was a nice surprise! As I was extremely tired, I had not done anything later that day, except that I assembled my bike, and unpacked all my bags. Yesterday I woke up at around midday, and after a nice lunch, I went for a relatively short acclimatization ride on the afternoon. (GPS details here.) My policy is the following: as I am on a work trip here, I only go cycling on those days, when I have no observing duties on the following night (because I might be in a good shape, but staying up all night and working with expensive equipment is not something you want to do tired).
First I went down to 2000 meter towards the NE (passing the famous colorful curves of the TF-24 road – see picture above), than I turned back, and climbed up almost to the point where I started, but as I felt still quite strong and I had still a lot of water in my bottles, I decided to ride a bit to the other direction on TF-21 towards the Teide volcano. It was really nice, with slopes between 4 % and 12 % (with 7-8 % most of the time).
I made two short videos about the roads and the scenery from the bike, which are not the best quality (as I had only my compact camera with me), but they can be seen here and here. It is worth checking them anyway, as you can see how my new cycling glasses fit me :) I think they are extremely cool ;D The road quality is not the best everywhere, but it is generally OK. There are silk-smooth parts, and there are places, where one have to be a bit more careful… After 50 km and 1000 meter of elevation gain, I arrived back well before lunch, so I had time to take a shower and check my mail before I joined the others at the table. Later that night I tried to stay up as late as possible (watching TV series on my MacBook) to shift my rhythm from day to nigh-time, but I had to go to bed already at 3 AM. Still I think it is OK, as I managed to sleep till midday today, so by the end of the forthcoming night, the shift will be complete. Now I am praying for good weather, because the last nights were a complete disaster for the previous observers, and we need data badly…

Time lapse movie showing the night sky and the scenes before and after an observing night at the Mercator Telescope situated on the island of La Palma among several other astronomical instruments of the Observatorio del Roque de los Muchachos.
Some interesting things to be noticed:
–Geosynchronous satellites visible as “standing still stars” in front of the “rotating background” of real stars, disappearing one-by-one starting from the bottom left corner as entering Earth’s shadow at 01:15 (only in 1080p size).
-Full Lunar halo at 01:33.
-Slightly visible zodiacal light at 01:04 (it is only slightly visible because of the strong moonlight, which lights up several night-time scenes later too).
-Frequently seen other telescopes are the robotic Liverpool Telescope and the Isac Newton Telescope.
-Venus (it is a planet indeed, but looks like a very bright star) can be seen setting above the horizon at 00:48 and 01:00 (Mercury is also visible to the lower right at 01:02).
-Several satellites, but also some meteors can be seen (e.g., at 02:35).
-Shadow cast by the mountain at sunrise can be seen on the clouds at 03:43.
-The last morning dawn scene was shot from the Roque de los Muchachos, which is the highest point of La Palma, 2423 m ASL.
Created from ~5000 individual photographs taken with a Canon EOS 7D + a Canon EF-S 15-85mm f/3.5-5.6 IS USM lens (usually set at 15 mm and wide open for the night-time shots). Original cuts were rendered in Photoshop CS4, then the movie was cut together in iMovie (this degraded the final quality slightly during compression).
As days get shorter (because they do, goddamnit), it is not that easy to go cycling after work (especially if you have troubles starting early at your desk, so you do not finish at 4 or 5 PM). One solution to this problem might be training before the working hours, which has advantages and – of course – disadvantages as well. First of all, if it was hard to get up at 8 AM on a usual weekday, then getting up at 6:45 will be even worse (believe me), but this way you might be back from a two hour ride by 9 or 9:30, and be at work after a refreshing shower at 10 already. You will need to stay till a bit later than usual, but then it will be already dark, so there is nothing to worry about (I mean, no lost hours of sunshine or anything). And you can skip the coffee on the morning, because the training will wake you up – guaranteed :) Plus you had success (hopefully) before work already, which makes starting the day much easier!
For me, the only problem with this system is that I am a night person, so going to bed before midnight is just not my thing. And then getting up so early is just terrible. But some sacrifices must be made… Though e.g. having a nice new jersey hanging on the doorknob gives the needed motivation to leave the bed! (And not just a jersey, but a complete Omega Pharma-Lotto kit – I love it!) The most important thing is to find motivation, because everything will be much easier when you have something (a goal) to get up for. Finally, I also managed to measure my resting heart rate (RHR = 53 BPM) for the first time yesterday (because when I am sleepy, this is the last thing I want to spend time on), so now I can set my heart rate values more precisely for the training zones. But I can not deny the fact, that after a morning ride, I need to eat much more during the day (I am hungry already before lunchtime), and I usually have a bad hour in the afternoon, when I feel a bit sleepy… But chocolate helps usually ;) By the way, my last three training rides were almost completely identical, I completed the 48.37 km measured part of my usual ~51 km route in 1:26:23, 1:26:36, and 1:26:44, respectively. This means that the difference was only 0.4% between the fastest and the slowest time! Fascinating, isn’t it?
Now it is raining, and there is no hope for good weather till next week… So I guess I will just work on the weekend, as I am nowhere near finished with my article… There are days when I am extremely productive, and then there are those when I can not make progress at all… Today was such a lousy day, fighting with scripts of my own, dealing with painful mistakes during long hours of debugging. I hope for a better day tomorrow…
Update (2010.08.28.): RHR = 46 BPM this morning, and an “almost personal best” ride (1:25:20, average speed of 34.0 km/h) in the wind! Now work :S
Tuesday was my last day on the Tour de France. As I already had ~900 images from the previous three days, I decided to leave the heavy equipment (and my press-card) behind, and hit the road on my racing bike, to catch the peloton at the one and only climb of the stage, at the Côte de Bothey (1.4 km climb to 3.4%, Category 4 – basically this is nothing, you can not even notice such a slope if you are riding in the peloton). Of course this meant that I had only my compact camera with me, so the pictures from this day are incomparable with the ones from the previous stages – but when you are not paid by a professional agency, then you have the freedom to choose between good pictures and just pure fun. That day I went for the fun only. We (as Tijl and Kristof – a postdoc and another PhD student, both from Belgium – did also join me on that day) left the Institute of Astronomy at 10:45, so we had three hours to our destination (as the expected arrival time of the riders at the climb was between 13:44 and 13:50, assuming an average speed of 46-42 km/h). As the distance was around 48 km, this was a very safe plan. The roads were generally OK, though we ran into some trouble with one-way streets in Wavre, and we had to ride on cobblestones for 5 km between Court-Saint-Étienne and Villeroux… I have to say that really do not like (or using the word “hate” might be more appropriate in this situation) the cobbles, but I tried to look at that part as the final stage of my integration into Belgium as a cyclist, which made me feel a bit better, and struggle a bit less. Still, the pain building up in my hands during these kilometers was incomparable to anything which I have ever felt on the bike before. And these were really the worst kind of cobbles, with large spaces in between the stones, and with a road-surface which was far from flat with a small bump running along the middle, and two small depressions along the sides (created by cars passing through). But this was the day when even the Tour riders had cobblestones (13.2 km compared to our 10 km, but on a route which is twice as long as ours), so at least we got to know the pain they had to go through later on… Anyway, at the end we arrived a bit more than one hour before the scheduled pass (just after the publicity caravan had passed).
The weather was really nice, sunny but not too warm, not too windy, with no chance of precipitation during the whole day. While we were waiting for the peloton to arrive, we asked someone to take a picture of us (check out the Hungarian flag which I brought along with me):
The breakaway group arrived almost exactly on the expected time, and the peloton followed them 4’45” later. We made some interesting observations about the whole stuff around us. 1) The number of support cars and motorcycles are incomparably higher than the number of cyclists. They are just coming and coming and coming for long-long minutes before and after the riders. And knowing that e.g. the team buses move along another route to get from the start of the stage to its finish, it is really shocking to see, that there are still this many vehicles following the peloton itself. 2) The climb was not big, still both the breakaway group, both the main pack was relatively slow after the “top”, so they probably just took a short recovery break there… 3) The gap of 4’45” felt surprisingly long.
After the closing cars passed, the organizers started to clean up everything very quickly, so we had to be fast to make a picture with the gate itself on the “top”. But we made it of course. (I know it’s way too over-photoshopped, but the lighting was terrible, and our “photographer” was and old French guy who probably took his first picture with a digital camera at that very moment…)
On the way back I tried to keep up with Kristof on the climb with cobblestones, and I managed, but as soon as we left the slope behind, he dropped me immediately. Yeah, he is definitely the King of the Cobblestones among us. (Though if there are no cobbles, no one can stop me ;D) But you really have to be a native Belgian to be able to ride fast on these roads. I think it is in their genes. When I arrived home (which is a mess now, with clothes and gadgets all around the place, as I had no time to clean up anything in the last days) I was still in time to watch the end of the stage with several paved sections (it was crazy!), then I left to play badminton with my colleagues… Yes, we have a very sporty department!
Now something for the geeks among us. I lost the second part of our ride, because I had only a one-way course loaded into my Edge 500 cycling GPS, so while we were riding back to Leuven, it was complaining all the time, that I was off-course, etc. Then after a while (on the biggest climb right after Wavre) it just died… So, if you want to follow a course back and forth, have both legs planned! And some interesting sites on the net for the Tour-fanatics: 1) You can follow the HTC – Columbia riders on Google Maps live here. 2) You can check the recorded data of selected Garmin – Transitions riders here. These are both really cool projects!
This brings us to the end of the story about me and the Tour de France of 2010, it was a great experience, a lot of fun but also hard work, and I hope to repeat it somewhen in the coming years. With a bit more sleep, if that is possible. Vive le Tour!
