 =====Log=====
+  [19:12:56] SESSION START
+  [19:12:56] obs arrival Sterling
+  [19:12:56] Active instrument: PICSARR2
+  [19:29:22] obs arrival Percy
+  [19:41:45] calibrations complete
+  [19:42:11] Slewing to arcturus for pointing
+  [19:49:49] Still exerpiencing problems with our focus encoder. We've learnedc from previous nights that the fix for this is to hit the cancel button on the motor driver chassis. But it may be worthwhile to try and identify the cause
+  [19:54:06] Pointing is complete but it is still too bright to begin captures, will wait 30 minutes for the sun to set further
+  [20:32:00] It is sufficiently dark, beginning captures
+  [20:32:55] Slewing to eta boo
+  [20:34:01] Eta boo acquired: It seems that it may still be too bright. Will wait another 30mins before beginning capture
+  [21:08:11] Changed the focsus to 1727.5
+  [21:08:35] It is actually sufficiently dark now.Beginning captures of eta boo
+  [21:27:57] Capture complete, slewing to HD 154445
+  [21:29:52] Starting HD 154445 capture
+  [21:54:18] Slewing to and starting Beta Cep capture
+  [22:21:46] Beta Cep capture complete
+  [22:21:58] Slewing to tau her
+  [22:22:21] Tau her acquired, beginning capture
+  [22:25:43] Clouds in capture
+  [22:40:48] Clouds cleared. Capture complete
+  [22:41:00] Slewing to eta boo
+  [22:41:49] Eta boo acquired, beginning capture.
+  [23:02:34] Eta boo Capture complete
+  [23:03:10] Slewing to HD 154445
+  [23:03:35] hd 154445 acquired. Beginning capture
+  [23:27:27] HD 154445 capture complete
+  [23:28:56] Slewing to and starting Beta Cep capture
+  [23:48:02] Slowing to and starting Tau Her capture
+  [00:04:59] Tau Her capture complete
+  [00:05:08] Slewing to eta boo
+  [00:05:19] Eta boo acquired, beginning capture.
+  [00:23:02] Eta boo Capture complete
+  [00:23:11] Slewing to HD 154445
+  [00:23:24] hd 154445 acquired. Beginning capture
+  [00:42:34] The skycover spiked suddenly, it is expected to be cloudy until 0300-0400et. This would render the night unviable for data reduction. So we have made the collective decision to shut down for the night.
+  [00:42:40] Beginning shutdown procedures
+  [0054] Shutdown procedure complete. Leaving the control room
