Sat Jun 17 18:24:48 GMT 1995: Patrol Start Sat Jun 17 19:00:57 GMT 1995: Calibration LOW-L COMMENT: Sat Jun 17 19:15:57 GMT 1995 Program crashed yesterday 6/16 01:20:56 ut while writing data to drive #0 on L00261. Slight drop in phase voltage from 118.0 v to 117.8 v at about the same time as the crash. Instrument head was stowed. Data writing switched from drive #1 to drive #0 mid-day yesterday, well before crash. Removed L00260 from drive #1 and installed L00263, removed L00261 from drive #0 and installed L00262. Will get the West data requested by Steve and then reset the computer to restart the program. Sat Jun 17 20:00:02 GMT 1995: Calibration COMMENT: Sat Jun 17 20:11:52 GMT 1995 Extended dome slot.

Sat Jun 17 22:00:59 GMT 1995: Calibration Sat Jun 17 23:01:02 GMT 1995: Calibration DPMON COMMENT: Sat Jun 17 23:05:20 GMT 1995 Instrument was progressively blocked by the dome for the last 30 minutes due to the problem trying to get all instruments to see the sun this time of day and year. Sun Jun 18 00:00:57 GMT 1995: Calibration MKIII COMMENT: Sun Jun 18 00:05:19 GMT 1995 Data has been very noisy this afternoon, difficult to see any changes. LOW-L COMMENT: Sun Jun 18 00:55:00 GMT 1995 Had six crashes between 2018 and 2214. Chart voltage dipped below 116v during that period, after voltage got above 116v there were no crashes. No obvious surges noticed during that period, the heater/fan was very inactive during that time also. The 486 didn't crash although connected to the lowl power strip. Cycling the power to the computer and the tape drives didn't stop the crashes. Something odd, when I tried to eject the tapes while starting up the lowl program they would rewind and stop without ejecting, then data would be written to the tape in drive #0. Maybe this is why the tape in drive #1 didn't eject yesterday when data suddenly started to be written to drive #0 in the middle of the day. I tried the manual eject button as we always do, on the front of the drive by the door. I recycled the tapes after each crash.
