Problems:
After running flatCheck, we see that flat fields are ok, buy Y filter that is very slightly out of the nominal value
We are measuring seeing below 1 arcsec, but ellipticities are above 0.05. The wind speed is low (around 5 mph).
03:12; It seems that the DIMM monitor stopped again, but around 4:00 it started to work again
The queue became empty during exposure 232366. We receipt the message about OCS:"Queue is empty. Disarming exposure queue." We disabled obstac and enabled it again, and it started to fill the queue again.
After the exposure 232366 (the last SNe SN-C3) the SISPI stopped loading exposures from the queue. We lost 10 to 15 minutes of data taking before realizing. We needed to press GO and it started again. Also all exposures before the SN disappeared from the exposures history in the observer 1 console.
Comments:
Claudio put the wind screen up to 20% because we have wind (at around 10 mph)
DIMM monitor is back.
