Greenwich sidereal time: 17:41:30 (17:00:00 UT) Sun's RA and DEC: 12h 31.1m -3d 21.5 =========================================================== Important Station Information Kokee is running warm. As a result, Kokee's SEFDs have been increased to 6000 for X-band and 1500 for S-band. =========================================================== There are no observations for Kokee and Wettzell from 18:15 U.T. to 19:45 U.T. Kokee and Wettzell will participate in the intensive session during this period. =========================================================== First observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Ke Kk Ma Ny Ww Wn Wz Yg 0202+319 18274-170000| 211 118 165 122 214 214 211| 1424-418 18274-170000| 20 20 | 1057-797 18274-170107| 49 49 | =========================================================== Last observations Source Start DURATIONS name yyddd-hhmmss Ft Ht Ke Kk Ma Ny Ww Wn Wz Yg 1936-155 18275-165404| 88 124 124 | 2002-375 18275-165442| 113 113 | 0700-197 18275-165558| 95 237 93 237| 0307+380 18275-165644| 83 83 | 1424-418 18275-165749| 126 126 | 1057-797 18275-165815| 100 100 | 0800+618 18275-165904| 51 51 51 | =========================================================== SKED Summary from file ./r1862.skd for experiment R1862 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 10.6 Min = 0.0 Max = 144.0 (Baseline Ke-Ny on 1741-038) RMS = 16.2 Total time: 1440 minutes ( 24.0 hours).
