Rainbow on the wy tot he Cumbre tunnel, BrenaAlta, La Palma
October 27, 2016

I spent quote a lot of time organising a visit for a large group (55!) of high school students. They’re Erasmus exchange students on an astronomy-related trip, some from Tenerife (the hosts) some from Poland, and some from Slovenia. The main point of their visit to La Palma was to see GTC, but they were going to be on La Palma all day, so what else could they see? So…


The ravens are back

October 5, 2016

I saw very little of the ravens over the summer. I think they were so many tourists with tasty food that they didn’t need me, thank you so very much. Now that it’s getting colder there are fewer ham sandwiches and almond biscuits to be had. Yesterday, my bag of cat food was back in demand. First they ate from my hands, as usual, and flew off. Then one came…



Today’s visit to Gran Telescopio Canarias was a bit different. Most of the group were bikers from Gran Canaria. It made for a good photo op as they left.

Foundations for the Large Sized Telescope

Digging foundations for the Large Size Telescope, Roque de Los Muchachos, La Palma 17/08/2016

Butterfly on a T shirt

Today I was doing my talk on the heliport, and this butterfly landed on a guest’s T shirt. I think it thought it was a flower. You can see the butterfly’s long tongue, looking for nectar.


Work starts on the Large Size Telescope

Work has finally started on the Large Size Telescope. The first stone ceremony was held on October 9th. This week the bushes have been cut down ready for the bulldozers to move in. Like the MAGIC, the LST will be a huge Cherenkov telescope (looking for gamma rays from space) with a mirror 23m across. The larger mirror will enable it to see fainter Cherenkov light, and therefore lower energy particles….
