EAA Observing Session: 31, January
This has to have been one of the most intensive observing sessions I’ve had to date. 10 observed principle targets, containing a total of 26 objects that have been identified and included in these observations. It was also unusual to have reasonable transparency throughout the session. Normally this is poor early on and starts to improve as we approach happy hour from about midnight onwards, where the seeing settles and the transparency improves. Session…
