 ATCA was in H75 configuration which is not ideal for VLBI: shadowing (note, no attempts were made to exclude shadowed antennas from tied array), RFI affecting auto-phasing (note, the phasing was less than ideal a few times; also manual phasing was issued once or twice in a response to large phase scatter observed in vis following the auto-phase. This was done during the same scan designated for auto-phasing). ATCA was in H75 configuration which is not ideal for VLBI: shadowing (note, no attempts were made to exclude shadowed antennas from tied array), RFI affecting auto-phasing (note, the phasing was less than ideal a few times; also manual phasing was issued once or twice in a response to large phase scatter observed in vis following the auto-phase.

 +Quite strong RFI observed in vis initially, but settles a bit by 08:30 UT or so.
  
 Real-time fringe checks revealed significant delay jump on AT baselines between different fringe finders. Based on the times fringe finders were observed, the jump occurred between 06:31 UT and 06:38 UT before the main science block started. ​ Real-time fringe checks revealed significant delay jump on AT baselines between different fringe finders.
