ISS Ops - 14 Feb 2022

Another quiet day but with cloudy skies, a southerly breeze in the afternoon, and a high in the low 50's.

ISS1 – All systems still running nominally.  Profiler status this morning: @ 0929 100m: 4.63A @ 50V & 1.838A @ 32V, and @0930 150m rass: 3.85A @ 50V & 1.885 A @ 32 V.

ISS2 – No issues again today with all green on the Nagios.

ISFS – Took a look at Sebastian’s 3D sonic to see if it could be mated with one of our tower mounts with no luck.  See Jacquie’s ISFS blog entry for pictures and details.

Soundings – A little breezy today during the sounding with a ~10 mph wind out of the SSW.  We filled the balloon by working through some of the empty tanks looking for any leftover helium.  Most of the tanks were completely drained, though we used the little bit left in two tanks to (slowly) fill the balloon today before attaching the hose to a full tank for the students and the morning launch.  There are two tanks on the right hand side of the trailer that are 100% full (blue arrows in image), the second of which I attached the hose to before we left.  Additionally, there are two more tanks on the left hand side of the trailer (yellow arrows) that I think were brought in by the U of U folks after the other tanks on that side were depleted.  How much helium remaining in those two tanks is unknown.  Tomorrow we will continue to check that the empty tanks are 100% depleted when we conduct the afternoon sounding.
