              ------------- ACTIVITY LOG --------------
Observing Specialist: P.Gaulme
Around sunset, some dust and few potentially rainy clouds that quickly disappeared. Clear sky then, with wind (gusts up to 23 mph) and seeing of 2 getting better at the beginning the second half, but then turning highly variable and bad (3-4 arcsec) from 2 to 6 am.
We noticed a small shift (about 1pix) of the DIS mask with respect to the boresight apperaring while rotating the instrument.
