E04 : Servo problem. C11 : Structural Repair. C09 : Painting. 28. Note for Backup :-- 29. Start and End Time of Obs.(IST): 17:55 - 01:00 30. ONLINE Machine : Shivneri 31. Comments (During Observations) : 17:55 : Started set up 18:16 : Started scan on 3C286. 18:26 : Stopped scan on 3C286. Note : S06 antenna has variation in amplitude. W06 : Apply brakes in Azimuth and hence there is no scan on flux cal. 18:28: Started command file. 19:02 : C09 release from painting and taken for observation. 23:00 : W06 Frequent ABC time out. 00:40 : Stopped command file. 00:44 : Started scan on 3c286 for ~15min. 01:00 : Stopped observation session.
