ISS 19 Jan 2022 IOP 03

Today at noon started IOP 3 which will go until noon tomorrow. We had been notified of a possible one yesterday but the go ahead came after noon today. Hopefully the rest of the IOPs are not short notice like this and luckily everything was working.

Today started out with clear skies and got fairly warm but in the afternoon it quickly became cloudy and cool and there was some wind.

Profiler perameters observed:

100m mode: 0925 50V @ 3.92A and 31V @ 1.845A

150m Rass mode: 0930 50V @ 3.49A and 31V @ 1.909A

Enclosure is still staying around 32C at the warmest time of the day

Today Isabel and I installed the large Ubiquiti dish and were able to recieve signal from the school so the wifi is a little better at the base trailer now.

The 1430 sounding today was a little rough. We ended up with 2 sondes that failed, both for RH above limits. With the first we initially restarted the software since it had failed for restarting during ground checks. When we tried the sonde again it failed for RH values over limit and the light would not stop blinking red.  We tried a second sonde and it also got the same failure. This time we rebooted the entire system. We tried this sonde again and same failure occured. On the 3rd sonde it made it through all the ground checks but then as Isabel took it off to set it outside, the sonde turned off. She redid the ground check and then it was fine and we sucessfully launched it. The 1615 sounding went smoothly and we gave a training to Alexei, who is a postdoc working on the project. During the 2nd sounding we retried one of the failed sondes but it immediately flashed red when it went on the ground test unit. The two bad ones are turned off and set off to side with notes on them.
