Summary: Reinstalled Peltier SHF plate, water in battery box, fixed RPi screen resolution, adjusted stardot clock

Varia
2015-12-23

I arrived about 9:30 with Siyan. It was clear, sunny and cool with a light breeze. There have been a couple days of rain. There are puddles on the road and the water hole is about half full, but the ground is not sloppy wet. I think the ground soaked up most of the rain. The trees have lost their leaves or all turned to brown. The grass is green but not growing very fast. A bunch of cows rushed over to wish us merry Christmas when we arrived.

I reinstalled the top Peltier SHF plate sn P01. I soldered it on to the existing cable and buried it at -2cm. I nearly cut the wire on SHF plate 0143 looking for some extra dirt.

The lid of the west battery box blew off and there was about 3 inches of water in that box and a dead mouse and mouse nest. I couldn’t figure out how to dump the water out without disconnecting all the batteries. I ended up digging out around the low corner and poking a hole in the box. This seemed to do the trick. We put the ladder on top of the boxes when we left.

Siyan collected the data and did spectral measurements. I fixed the screen resolution on the Raspberry Pi. The screen was reporting a resolution of 1280x1024 at 60Hz, I set it to 1024x768 at 60Hz. Looks like all the images were collected. The StarDot clock was about 12min fast. I reset it at from 10:10 to 9:58. The Raspberry Pi is still on UTC.
