No of Antennas Working(Fringing) at the beginning :28 32. Name of Non-Working Antennas (with reason for each) : C08 : BLDC Installation. E04 : Feed cage painting. C14 : Servo timed out. W03 : Frequently getting reset. 33. Note for Backup : 34. Start and End Time of Obs.(IST): 11 Feb 2016 05:00:00 - 11 Feb 2016 09:00:00 35. ONLINE Machine : Lenyadri 36. No of Antennas Working(Fringing) at the end :26 37. Comments (During Observations) : 05:10 : Started command file. 08:15 : Power failed. Stopped command file. 08:45 : Power and setup recovered. C14 got servo time out. Due to high electrical voltage C00,C14,W03,W04 started giving problem. Still recorded phase cal for 5 mins. 08:51 : Stopped scan on phase cal. High voltage for electrical. Please ignore scan nos. 9 and 10. 09:03 : Started once again scan on 3C286. C14 and W03 still problem persists. C00 and W04 recovered. 09:23 : Stopped scan on 3C286 and closed observation session.
