LA is writing Mark V disc pack NRAO-041 in bank A. KP is writing Mark V disc pack NRAO-052 in bank B. VCLOCK, GPS Delta, and UT1-UTC check ok. 2241 Begin at all sites. 2241 WEA: Web cams show clear skies at BR and MK, partly cloudy skeies at HN, FD, LA, PT, KP, and OV, cloudy skies at NL. Its dark at SC. 2249 *NL WEA: Raining. 2337 *FD WEA: Wind gusts > 35mph. 0000 Date is 2005FEB28/059. 0029 *PT WEA: Snowing. 0033 All readbacks ok. 0118-0119 *SC AZ #1 armature overcurrent. I disabled ACU 100 1 the AZ axis for a couple seconds to clear the fault. 0238 New operator is Jim Ogle. 0246 Readbacks okay. 0403 Readbacks okay. 0421-0630 *SC AZ#1 armature overcurrent fault. Fault not 15766 100 129 cleared by disabling AZ axis or by putting antenna in standby mode so a fuse is probably blown. Stowing antenna and calling out site tech. 0428 &SC tech Greg Worrell contacted, on his way out. 15766 0510 *OV bad readbacks on track 5, drive #2. Other sites okay. 0602 &No sign of Greg at SC yet so I tried calling him 15766 on his cell, no answer.
