Sky looks clear. ___end___ GENERAL COMMENT BY waters: Thu Apr 16 17:05:05 GMT 2020 PM Blew off Kcor O1 ___end___ GENERAL COMMENT BY waters: Thu Apr 16 17:05:17 GMT 2020 Windows opened upstairs ___end___ Thu Apr 16 17:11:17 GMT 2020 KCOR Start Synoptic Patrol GENERAL COMMENT BY waters: Thu Apr 16 17:37:07 GMT 2020 The two streams have popped up. Three bullet holes can be seen in both but the locations are different when looking at the two. The NRGF has them from the Southwest to the Southeast while the normal stream has it from the South to the West. There are also two artifacts in the the west and Southwest. Going to see if I can go up and address them. ___end___ Thu Apr 16 17:37:28 GMT 2020 KCOR End Patrol Thu Apr 16 17:37:28 GMT 2020 KCOR End Patrol Thu Apr 16 17:45:27 GMT 2020 KCOR Start Synoptic Patrol GENERAL COMMENT BY waters: Thu Apr 16 17:50:59 GMT 2020 I could see two artifacts on the front side of the O1 that are very stuck on the lens. However, I think some of the bullet holes are on the back side of the O1. Blowing off the front did not remove the bullet holes and I do not feel comfortable yet with handling the O1 alone to blow off the backside. However, the artifacts that were in the Southwest and West left the lens before I started blowing off the O1. ___end___ Thu Apr 16 20:26:19 GMT 2020 KCOR End Patrol Thu Apr 16 20:26:22 GMT 2020 KCOR End Patrol GENERAL COMMENT BY waters: Thu Apr 16 20:31:23 GMT 2020 Dec was acting up, it started increasing it's arcsec error in the positive direction over the one minute interval and just kept going. There wasn't any gusts of wind that I could tell and nothing impeding the spar but putting the lens in Kcor and switching from open loop to close loop seemed to fix the trend. Will keep an eye on it. ___end___ GPS COMMENT by MLSO: Thu Apr 16 21:45:06 GMT 2020 Successfully logged in to system Good disk mount GPS software running Last 5 GPS data files are: /mnt/usb/dataoutiq_2020_102_2146.bin 2147483647 /mnt/usb/dataoutiq_2020_103_2146.bin 2147483647 /mnt/usb/dataoutiq_2020_104_2146.bin 2147483647 /mnt/usb/dataoutiq_2020_105_2146.bin 2147483647 /mnt/usb/dataoutiq_2020_106_2146.bin 2147483647 ___end___ GENERAL COMMENT BY waters: Thu Apr 16 21:45:01 GMT 2020 Dec error went rogue again.
