Just few clouds at west horizon at sunset, sky is clear.
Dewpoint at -16\xB0C and external temperature at - 15\xB0C
There is a difference about 12/13 degres between primary mirrors and external temperature
We have to wait changes in weather conditions.
After few hours the external temperature falls down to -19\xB0C, the mirrors temperature is still far from the external temperature. At 3:30 the TO decides to not open the dome for this night ( we are almost at -20\xB0C)
