ACE Arctic Validation Campaign
As the clouds roll in - March 2
How the morning unfolded:
9:09 am: At first, there was a glimmer of hope
9:31 am: Maybe the cloud bank will stay put...
10:01 am: Is it really getting thicker?
10:31 am: Were we expecting a another storm?
11:01 am: So much for the solar measurements today!

The rest of the day: a faint glow did appear in the sky but not enough to track or measure.
