The first NRGF image at 17:46:02UT looks clean but the next image immediately has crosshatching in the Southwest corner and less noticable ones in the North. Was seen in Saturday but not logged and could be seen in the Sunday stream data I caught this morning as well. Start up was done as usually, no bumping of the spar, no opening or moving of anything after Ben did the occulter change on Friday. As Joan and Giuliana pointed out, we have seen this fringing before. However, we are not sure what could have changed between shut down on Friday and start up on Saturday if nothing out of the ordinary was done to the spar/instrument to cause the fringing. Note that the first image after todays calibration was also free of fringing in the NRGF at 19:32:13UT before they reappear. ___end___ KCOR COMMENT BY waters: Mon Mar 18 19:42:17 GMT 2019 Either I started the calibration with the Science data not illuminated or the sequence did not re illuminate it once the calibration script was done. Either way, Science Data button should have been illuminated at 19:31:11 GMT. ___end___ Mon Mar 18 20:09:12 GMT 2019 KCOR End Patrol Mon Mar 18 20:09:32 GMT 2019 SGS Alignment complete Mon Mar 18 20:09:35 GMT 2019 KCOR Start Synoptic Patrol Mon Mar 18 21:54:37 GMT 2019 KCOR End Patrol Mon Mar 18 21:56:06 GMT 2019 SGS Alignment complete Mon Mar 18 21:56:07 GMT 2019 KCOR Start Synoptic Patrol Mon Mar 18 23:30:21 GMT 2019 KCOR End Patrol Mon Mar 18 23:30:36 GMT 2019 SGS Alignment complete Mon Mar 18 23:30:38 GMT 2019 KCOR Start Synoptic Patrol Tue Mar 19 00:18:26 GMT 2019 KCOR End Patrol Tue Mar 19 00:18:43 GMT 2019 SGS Alignment complete Tue Mar 19 00:18:45 GMT 2019 KCOR Start Synoptic Patrol Tue Mar 19 01:51:22 GMT 2019 KCOR End Patrol ONSITE STAFF: waters
