Finally, the third night brought good weather over Tenerife. The humidity was still not low enough to have cloudless skies (so no photometric conditions), but what is not good for astronomy, that can be perfect for photography. The clouds at the peak of the Teide were amazing.

And as the sunset came closer, the colors and shapes kept changing continuously. Then – as almost every day – the shadow of the volcano was again visible over the sea towards Gran Canaria as the Sun moved below the side of the mountain. Yes, what you see below is the shadow of the mountain’s slope (the dark rays from the middle towards the top right)!

There were some clouds during the night, but not that many – most of the time only the Teide’s lenticular cloud was hanging over the moonlit landscape. I made a time lapse again, which can be seen here. I have some nice things to show in tomorrow’s post already (it was really hard not to include it right now)!

Ok, the second night was not good for science. Again. This is a bit strange, as I usually do not have 2 consecutive nights of bad weather. As far as I can remember, it only happened once, during a really harsh winter in Hungary. Anyway, the humidity was too high to operate the telescope (80-100%).

But at least, the atmosphere started to clear up, and the dust was gone already, so I had high hopes about the forthcoming night (which happens to be right now, when I write this – and yes, I was right, we are getting data at the very moment). Still, as it was not sure, that the humidity would stay high all night, we stayed at the telescope. In the third quarter of the night, some clouds came from the NW, and stayed until sunrise, creating a beautiful background for my pictures.

Finally, for the first time since I am on the island, I could see Grand Canaria and La Palma in the distance (as the atmosphere became clean enough for it). There were amazing lenticular clouds on the sky again, formed by the uplift from the slopes of the Teide volcano.

I really wanted to leave as soon as the time lapse of the night was finished (though I made a minor mistake after I changed the batteries for the first time during the night, the video can be seen here), but I could not, as the landscape was so amazing, that I had to take pictures for like a half hour until I finally managed to go down to the residencia.

There – thanks to the guy at the kitchen (not the chef, but the one who usually works as the “waiter” there) – I had a really good, typically Spanish sandwich with smoked ham and tomatoes for breakfast, then I went to sleep. Yeah, sleeping from 9:00 to 17:00 is normal for an astronomer ;) And before I forget; you can find all the pictures I have taken so far on my flickr gallery here. I try to update it every day with a selection…
