| - | xxx | + | March and April are busy months with numerous visitors coming to the site. BYUCam on ARCSAT is ready for community use. The Agile image timestamps are accurate but the sync issue is still being investigated. The ARCTIC diffuser rotation issue that was seen during cold temperatures has been fixed. The control software is not giving a valid rotation flag (i.e. when it is rotating at speed the flag is not registering). We recommend that users continue to use the instrument (with the diffuser rotation) as is. It looks like the rotation is still happening at proper speed; it may be slightly below the nominal 2 Hz threshold but until Bill can take it apart and clean it we won't know for sure. For this week, as long as the star's diffraction spikes are being smeared out it should be considered acceptable for science (if not, we recommend defocussing the instrument a bit). There is an issue with a ghost image in the TripleSpec data that Russet is investigating. We are meeting with Lowell Observatory engineers next week to discuss M1 realuminization. Users are urged to upgrade to python3 if they have not already done so, and to use the latest python3 version of TUI. Because python2 is no longer being supported we will not be able to support or troubleshoot the python2-based version of TUI any longer. |

| - | xxx | + | When Sarah was at APO a couple of weeks ago she spent some time looking at the smear users were seeing in the overscan with bright lines. She played around with some voltages to check if it is due to a serial readout problem. Of note to all KOSMOS users, the way the detecter controller is currently working, it shows as being saturated at the ADC maximum, not the chip full well depth, meaning it will go up to 2^18 counts before it overflows. Somewhere between 150k-200k is the physical full well. She is still doing tests to quantify this, but **KOSMOS users should be aware that very high count levels (> 150k) are not physical.** Sarah got some help from a CTIO colleague who worked on COSMOS and got the information she needed so now she can test the voltages. The chip is currently optimized for a single amplifier but the goal is to be able to run it using one OR two amplifiers. The instrument is currently in a stable state and we will always leave it in its default state after testing. That said, users should notify their observing specialist and Sarah Tuttle if they have questions or encounter something out of the ordinary. |

| + | Joanne is coming to APO in May and hopes to have the files ready for slit mask production by end of this week. She offered to test other slit masks if users have any additional masks that they would like to get tested. | ||
