Summary: Collect data and check tower

Twitchell
2011-12-28

I arrived about 11:30 PST with Kyoko and Hisashi. It was sunny but hazy and there was almost no wind. On Brannan Island just north of Twitchell Island, there were huge flocks of geese and swans, but almost no birds on the fields at Twitchell.

I collected data. All looked well though the LGR pressure was low again:
11:35PST, 29.57C, 86.85Torr, 13.922usec, 10Hz, 2.631ppm

In low flow the pressure was 116Torr. I adjusted the bypass valve to bring the pressure up to 148.13Torr. When I left the LGR was back at 10Hz.

The fan for the HMP45 didn?t seem to be running.
