A blog about a system to determine terrestrial albedo by earthshine observations. Feasible thanks to sheer determination.


Observing logPosted by Peter Thejll Dec 29, 2011 09:23AM
At sundown T=8.8 wind dropping, 10-14 m/s, RH about 20%. 2 hours later outside T was 5 degeres C while dome T was still 7.

Shutter failing often - and 'open while reading out' occurring. Again we see sets of images failing. Of course not related to the physical filter itself - but then why e.g. all VE1 images failing while adjacent images OK?

No clouds. halo starting to reach DS edge towards sky.

Noted that an antenna gets in the way of the Moon during some Moonsets.
