Telescope Operator: Steve Allanson, Geno Bechetti
Support Astronomer: O. Kuhn (on call)
Instrument: MODS

Summary

Before the sunset the sky was partly cloudy, humidity was at 32% and there was a low wind.
Some problems with modsView and modsAlign in the station obs2, after few check it
seams to be caused by the Ob directory "Antoniucci Bckup".
After the execution of the Antoniucci_bckup OB the sky became clear and the seeing good.

Summary

At the beginnig of the night light SNOW and wind.
At 3:30 no snow but heavy clouds.
At 4:30 completely clear sky, we can't open the dome because of 2-3 inches of snow on the roof. (Mike go up to check the situation)
The TO and John Little agree to stay close and re-check in a couple of hours.

Summary

At the beginnig of the night strong wind 30m/s S-SW stable. Gust around 36m/s.
42% humidity, clear sky!!!
At 6:30 wind is around 22 m/s and the humidity rises to 90%.
The last hours of the night the humidity riches 100 %, dome remains closed.

28 marzo 2014

Summary

Late afternoon the humidity is 102%, outside temperature -2.5 C, dew point temperature -2.2 C, wind around 14 m/s.
Due to the dew point limit, we can open the dome, and the temperatures are : chamber=3.48 C, glass = -0.47 C.
Heavy clouds just on top of the telescope.
the situation go better and we open the dome: temperatures of the glasses are: -0.4 C on the left and -0.8 C on the right, the external is -4 C and the chamber is -3 C.
Problems with the temperature gradient on the mirrors, the focus is not very good.
During the transit we had problems with the blue shutter. It remains stuck opened and we need to stop the ob and operate with the SA every one/two images.
During the transit the seeing value oscillate between 1.4 and 2.9.
We lost about 17 minutes of images during the last part of the transit.

Summary

We should have used LBC, but the problem with the blue shutter still persists. We use MODS.
Some cirrus at the beginning of the night. Humidity 9%.
