Comments: 

Program almost complete. 2 targets skipped.

Second observation of HD 13516 skipped, unable to observe it after 4 hours at it reached the telescope’s limits.

RKS0431+2501 no time for it.

Last northern targets were hard to get, HA>2, way to East. The listed limits are more optimistic than real limits. The telescope got stuck and it took me a whil to recover it (time lost 0.25h), please consider this for next programs.

Seeing data from DECam.
