Channel 1 had problem on the first day.

Problems:

One problem that we encountered on the first day was pointing fluctuation with a slow scan rate of 3"/sec. The data recorder shut off when the fluctuation exceeded tolerance. But this intermittent data recording irritated MAC and kept giving us trouble. We changed to a faster scan rate of 8"/sec near the end and the problem was gone.

Resolved:

Hours_lost_weather:

We lost about 2 hours on the second day due to gusty wind blowing the vane in and out. We couldn't even point and focalize. We resumed later on and everything was fine till the end.
