----------------------------------------------------------------------------- Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Wed Oct 30 16:37:05 GMT 2013 Year: 13 Doy: 303 Observer: berkey WEATHER COMMENT: berkey: Wed Oct 30 16:37:10 GMT 2013 temp 39f, wind 16mph from SE, patchy cirrus, lots of ice on the ground around the observatory. ___end___ WEATHER COMMENT: berkey: Wed Oct 30 16:55:44 GMT 2013 Some fog quickly blew in from the SE domes are closed and instruments are safe. ___end___ Wed Oct 30 20:22:43 GMT 2013: PSPT Start Patrol KCOR COMMENT BY berkey: Wed Oct 30 20:47:36 GMT 2013 Kcor cameras were aligned taking data with the distortion target in the beam. Current there is a little hair on the target I will take a second set with the hair removed. ___end___ KCOR COMMENT BY berkey: Wed Oct 30 20:49:34 GMT 2013 oops not guiding re-aligning the spar. ___end___ KCOR COMMENT BY berkey: Wed Oct 30 20:55:57 GMT 2013 Hair removed from the target and target reinstalled. ___end___ GENERAL OBSERVATORY COMMENT BY berkey: Wed Oct 30 20:58:59 GMT 2013 False positive on the safty lanyard. I got a call on my cell about trouble at teh Mauna Loa solar observatory. ;( I wasn't hurt and no call went out to UCAR security. ___end___ KCOR COMMENT BY berkey: Wed Oct 30 21:02:40 GMT 2013 Installing kcor occulter r=1018.9" ___end___ Wed Oct 30 21:25:26 GMT 2013: PSPT Start Patrol Wed Oct 30 21:39:19 GMT 2013: PSPT Abort Patrol Wed Oct 30 21:39:23 GMT 2013: PSPT Abort Patrol GENERAL OBSERVATORY COMMENT BY berkey: Wed Oct 30 21:48:42 GMT 2013 Domes closed due to fog ___end___ Thu Oct 31 00:26:48 GMT 2013 COMP Start Patrol WEATHER COMMENT: berkey: Thu Oct 31 00:28:59 GMT 2013 Sky clear of clouds, but brightness is still a bit high. ___end___ CoMP COMMENT BY berkey: Thu Oct 31 00:31:27 GMT 2013 This morning between other work on kcor I found that the comp camera was canted w.r.t its alignemnt ring, likely from hitting the ladder (or something similar last week). This is consistent with the slightly off round and poorly center images we were seening from comp from the last week or so. This problem was addressed by loosing the ring and moving the camera until it was well seated to the ring. At this point the images looked round and farily centered with the diffuser in. It wasn't until a few minutes ago that the skies cleared up enough that I could check the occulter alignment. The occulter was close but aligning it helped to get a better centering of the image on the detector. During the process of loosening the ring,the camera rotated around the optical axis a bit (>10degrees). In re-aligning the camera I rotated it such that the mechanical structure of the camera appeared to be square with the mechanicl sturcture around the optics box. As far as I can tell CoMP now has a decent alignment, but we dont have good enough skies to get data on this today. ___end___ Thu Oct 31 00:41:44 GMT 2013 COMP End Patrol Thu Oct 31 00:50:43 GMT 2013: PSPT Start Patrol GENERAL OBSERVATORY COMMENT BY berkey: Thu Oct 31 01:12:29 GMT 2013 Fog blowing up from the saddle ___end___ Thu Oct 31 01:27:48 GMT 2013: PSPT Abort Patrol Thu Oct 31 01:27:51 GMT 2013: PSPT Abort Patrol Thu Oct 31 01:27:55 GMT 2013: PSPT Abort Patrol KCOR COMMENT BY berkey: Thu Oct 31 02:19:25 GMT 2013 I did a foreoptics inspection on K-cor this afternoon. The O1 is starting to collect a little bit of dust approximatly similar levels to what CoMP collects. So the hepa seems to be doing a pretty good job. It is almost time to do a cleaning on the Kcor and CoMP O1's both are starting to pick up a nice coating of the small dust particles that done blow off. The K-cor O1 in particular has a bit of a water stain that looks like it got on the lens during the last cleaning. On an intersting note there were two dead insects on the k-cor o1 lens cell neither were in the beam; but I couldn't find any other insects in teh foreoptics area. ___end___
