458204:45-04:50, 07:25-07:3000:10TTP camera not making offset corrections unable to make automatic guide corrections in TTP; have to manually move into position
458407:30-07:4500:15During first science test trajectory of the night found that offsets for guiding are not working on any of the cameras. Tried acqcam, guider 1 and guider 2 ... no auto guiding available on any of the cameras. markers come up but no physical movement is seen on the camerasable to move manually and with telescope offsets but guiders not guiding.


Ops Commentsnone


TO Commentsfound that none of the guiders are auto guiding which includes TTP, ACQ, gudier1 or guider2...


RA CommentsLRS2 partially operational (no R channel). Threatening clouds at sunse: no skyflat taken. Took CWFS,WFS1,WFS2 data set for HL using GOES-14. Problems with guiding at 7:45UT about the same time that increased cloud cover arrived.
