Mauna Loa Solar Observatory Observer's Log ----------------------------------------------------------------------------- Tue Dec 13 16:55:52 GMT 1994 Year: 94 Doy: 347 Observer: koon WEATHER COMMENT: Tue Dec 13 16:56:05 GMT 1994 Clear, wind 20 mph from the SE, temp 35 F. Tue Dec 13 17:18:47 GMT 1994: Patrol Start LOW-L COMMENT: Tue Dec 13 17:20:33 GMT 1994 I copied the *.c and *.h files from the lowl directory to disk for David Elmore to look over, did that last night after the observing day. Also removed L00145 from drive #0 and installed L00146 in drive #0 and L00147 in drive #1. DPMON COMMENT: Tue Dec 13 17:23:24 GMT 1994 Getting some kind of optical runaway, probably diffuser and Daystar filter. Pausing Patrol to correct it. Tue Dec 13 17:26:32 GMT 1994: Patrol Start DPMON COMMENT: Tue Dec 13 17:32:45 GMT 1994 Having trouble adjusting the occulting disk position, will pause Patrol and manually check it out. DPMON COMMENT: Tue Dec 13 19:53:54 GMT 1994 Couldn't find any broken wires or blown fuses, can move occulting in N-S direction only. Connected hand-box to power supply jumper cable at OCP and tried it (to bypass OCP microswitches) but still can't move E-W, so power supply does work. I'll check the DC motors and cable actuators up on the spar. DPMON COMMENT: Tue Dec 13 21:07:04 GMT 1994 Found two broken wires in the D-connector at the junction box side of the cable that runs to the DC X-Y motors on the Spar. I'll have to remove the entire cable and possibly resolder all the wires on connector. Problem was caused by cable snagging yesterday afternoon. COMMENT: Tue Dec 13 21:26:59 GMT 1994 Spar was temporarily off target while I removed the DPMON cable for repairs. Tue Dec 13 23:13:32 GMT 1994: Patrol Start DPMON COMMENT: Tue Dec 13 23:13:35 GMT 1994 Fixed the Occulting X-Y cable, ended up resoldering 4 wires (2 broken, 2 frayed), cables are routed so that snagging shouldn't happen again. COMMENT: Tue Dec 13 23:15:29 GMT 1994 Depletion noted in last image difference at PA=300, approx. 2210 ut. Probably corresponding to what looks like a surge at same PA, didn't get any images with DPMON until now so I don't know what that area looked like earlier but the surge is out to RV=1.15 now. I don't see any CME signature but I could have missed something earlier while working up in the dome.
