It looks as though NASA's Infrared Telescope Facility (IRTF) on Mauna Kea is closed. In fact it isn't, it's just the dome turning its back to me. The open slit is facing 180 degrees away and the telescope is observing something in the orange twilight sky above the usual sea of clouds.
So here's a puzzle. The IRTF spends a lot of time observing planets in our Solar System and there's a good chance it might be doing that. This is around 7:05pm local time on the evening of August 11th - it's looking roughly north-northwest. Anyone hazard a guess as to what the observers were looking at?
