The skies clear in anticipation of seeing the full Sun...
After a cloudy night, we awoke to clear skies with a little cloud on the horizon. Michael had not gone to PEARL to take DIAL measurements because the 0PAL lidar showed low cloud overhead.
Annemarie finished the UT-GBS setup and installed the instrument on the roof. Then she spent the rest of the morning working on the SAOZ communications problem with me. The issue was isolated when Annemarie opened the interface box and we found that the power supply was set for 220 V not 110 V. SAOZ was much happier once it knew it was in North America. In the afternoon, we dismantled the support structure in the SAOZ hatch and modified it so that it would fit the new instrument case. Thanks to Oleg for his help with this.
Richard had a successful day testing the DA8 and running the tracker. He realigned the detectors and everything is working as well as it did last year. The tracker was able follow the partial Sun for about 30 minutes and Dejian and I tried putting in the PARIS-IR mirror to do a quick solar alignment test. Unfortunately, we were not quick enough as the Sun disappeared before we could finish the test.
Tobias and Tom continued to set up the SPS processing software. Clive ensured that the MAESTRO and SPS measurement schedules were set up correctly in anticipation of sunrise tomorrow. Unlike yesterday, there were no power outages. The main technical issue was a short network outage at PEARL that Paul and Pierre dealt with quickly.
Best regards,
Kaley.
