The Roque de Los Muchachos is a spectacular place to watch the sunset. For one thing, you’re usually above the clouds (which is one reason the observatory is there.) In fact, sometimes the clouds are so much lower than the Roque that the sun sets well below you. This means that your shadow on a wall is taller than you, and the shadows of your legs go on forever….
The Cherenkov Telescope Array (CTA) is negotiating with the IAC to site more Cherenkov telescopes on La Palma. It’s not guarenteed that they’ll come here, but it’s highly likely. What is certain is that they’re going to build a prototype here. So what’s a Cherenkov telescope? The oversimplification is that it’s a telescope to look at gamma rays instead of visible light. For more detail, see this article on…
Tuesday was great too. I took the journalist, Tim Johnson, into Santa Cruz, where he bought a T shirt. Then we went to Las Nieves and thence to San Andres (via the usual viewpoints) to stuff ourselves at Restaurante San Andres. I love their fishballs! After that we did a short hike in Los Tilos, and went round the north along the Mimbres road to Hoya Grande, and up…
For centuries, goatherds have brought their flocks to the Roque de los Muchachos, the highest point on the island of La Palma. As the lower pastures dried out in summer, they moved to fresh pastures on higher ground. These days, farmers can drive home for the night, but of course that wasn’t the case 50 years ago, much less 500 years ago. They came up some time in June,…
It must be summer. The plain swifts (Apus unicolor) are back at the Roque de Los Muchachos. These birds are native to the Canary Islands and Madiera, but some overwinter in North Africa. I don’t know where these ones disappear to in winter, but it’s always nice to see them back, zipping acrobatically around the telescopes.
Spring is obviously here. Some people look for the swifts returning or flowers blooming, but I know it’s spring when the solar telescopes start work after their summer break. It’s not very easy to see whether the Swedish Solar Telescope is working unless you’re close, but yesterday, the Dutch Open Telescope had the clamshell dome down and they were clearly open for science. It must be time to buy…
