Some\nfields were visited more than once. Each visit consisted of 1080 seconds\nin the w filter. Our observations are listed below. Analysis is\nproceeding.\n\nDue to hardware problems (a failed CCD power supply and a jammed\nfocuser), we only observed with only four of the six telescopes and\nobtained about 48 square degrees at each visit rather than the full 72\nsquare degrees.\n\nWe thank the staff of the Observatorio Astron��mico Nacional in San Pedro\nM��rtir.\n\nStart (UTC)       RA and Dec (J2000)\n2019-04-27 06:03  21:40:22.6 +85:17:25\n2019-04-27 06:33  21:40:22.6 +85:17:25\n2019-04-27 07:00  21:40:22.6 +85:17:25\n2019-04-27 07:26  20:50:51.8 +63:40:00\n2019-04-27 07:53  20:50:51.8 +63:40:00\n2019-04-27 08:20  20:25:31.7 +47:46:54\n2019-04-27 08:47  20:16:56.0 +39:52:13\n2019-04-27 09:13  20:36:33.3 +56:11:28\n2019-04-27 09:40  19:59:21.3 +24:29:14\n2019-04-27 10:07  20:05:19.9 +31:51:18\n2019-04-27 10:34  21:40:22.6 +85:17:25\n2019-04-27 11:01  23:55:06.2 +83:59:48",
