Update: The activity has been cancelled due to bad weather.
Astrotour are offering the chance to see comet Pan-STARRS through a telescope for free.
You just have to turn up at Mirador de las Brujas on Saturday 16th at 7pm, but be sure to bring warm clothes (it’s over 4,000 ft) and something to eat. Hot drinks are probably a good idea too. It’s also a good idea to bring binoculars, and a camera and tripod if you have them. Astrotour will give advice on photographing the comet. There’ll also be a chance to see Jupiter through a telescope and learn some constellations.
I hope to be there, so there should be a chance to buy my guide book to the observatory. And I might (might!) have the Spanish version by then.
