07:20 : 
IMPORTANT NOTE: Noticed that, source lists not getting loaded to TGC system via scripts/command file. this affected first target HS1237 instead of it system continued scan on 1252+565 (phase cal). 

10:11 : Scan 13 bad for last 2 min data records, due to command failure.
10:25 : C00 and C08 taken for maintenance work.
11:41 : Started scan on 3C286 for ~ 8.58993 min.
12:00 : Observations session over.
