*** NOTES

* Dome opened between 03 and 09 UT (clear-sky window)

* Due to poor/unstable seeing conditions, at the beginning of the observing night we need to focus each image 

* Observation of LSQ13bah aborted since no clear transient was detected in the aquisision images  (~04 UT), needs better seeing

* PSNJ01364816+1545310 aborted due to clouds (~09 UT)
