              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
The early evening started clear but clouds gathered as soon as the sun set.  There were scattered showers in the area on radar, but they started to disperse around midnight.  We opened, and remained open.  There was a period from 0200-0300 where though we remained open, the skies were too cloudy for data, and the observer took cals instead. By 0300 the clouds blew out, and it was clear until morning. Ecam was tested through the night, and is still showing signs of that brighter stripe to the left-hand side.
