File count reset sometime 4/19 early on. Reset again this morning. Program would not respond to 'q' command to quit so I could reset the program and change tapes. Ejecting L00508 manually and moving L00509 to drive 0. Loading L00510 in drive 1 and rebooting PC.

Error flag set (RED). I was awaiting instructions on how to handle the problem found yesterday, where the primary drive failed and data was writing to secondary bank. Tape change did not fix problem. Net down due to testing so I have not received response from GONG. PSPT COMMENT: Tue Apr 21 17:33:01 GMT 1998 PSPT failed to point correctly this morning. Light beam missed the lens by around 1/3 diameter. Exited and tried Run again but this time guider attempted to point farther and farther away from sun on initialization. hot rebooted PC and exited program on Sparc. exited (parked spar and dome) and trying Run again. PSPT COMMENT: Tue Apr 21 17:54:57 GMT 1998 Sounds like there might be a mechanical failure in the dec drive. Position again tried to go negative by a large amount -- kept running on away from 'home' (50000). When I exited program, it tries to home again to park position, running a long way back to 50000, but I can hear something clunking softly inside the declination drive and the spar is not moving.

PSPT COMMENT: Tue Apr 21 18:18:39 GMT 1998 PSPT is probably messed up, 'stat mnt' should show RAp=100000 and DECp=50000. I reset the PC so it now shows both values=0 Haosheng did not tell us how to reset the correct values. There is also no procedure documented to open the covers so we can point the guider to the sun by looking at the beam on the lens in the optics bay and do a 'gdr ephmcal' or some other routine to put the correct values into the PC. I will not deal with this now as there is an EPL and CME in progress. MKIII COMMENT: Tue Apr 21 18:28:53 GMT 1998 H-alpha material visible, moving thru the corona.

Just got a 'wrote 0 records' error and tape stuck in Write scenario. I will wait for the CME to finish before changing tape. The data is going to disk anyway and do not want to interrupt. PICS COMMENT: Tue Apr 21 19:33:23 GMT 1998 EPL completely faded now. PSPT COMMENT: Tue Apr 21 19:47:23 GMT 1998 This time PSPT got past homing the guider. It may work this time.
