Bad weather at Paranal
I’m at Paranal right now, undergoing my final training before they let me fly solo at the controls of the world’s premier optical observatory. My training so far has been seriously affected by weather – of the 11 nights I’ve done, five have been completely lost and most of the rest have been partly lost. Last night the telescopes were closed a couple of hours early, and tonight we didn’t open at all. The telescopes have to be closed when the humidity goes above 60%, and tonight it was nearly 100% and there were clouds right on the peak.
Before the clouds came in, though, I went out to take a photo of the night sky. The moon was rising, and Orion was setting. When I took the photo, I couldn’t see the shadow the moon was casting, so I was pretty amazed when I looked at the camera screen to see the shadow of the telescopes, cast on to the clouds below.
