We observed ASKAP J005547.4-270433/AT2019osyNot found
 
 
 (GCN 25487Not found
 
 
) with the
Australia Telescope Compact Array (ATCA) on 2019 September 6
from 12:30-19:30 UT.

We report flux densities of:
  380+/-21 uJy at 5.0 GHz
  353+/-17 uJy at 6.0 GHz
  299+/-14 uJy at 8.5 GHz
  234+/-14 uJy at 9.5 GHz

Which are consistent with the measurements obtained with the ATCA on
2019 August 29, 8 days prior (GCN 25487Not found
 
 
, GCN 25621Not found
 
 
, GCN 25539Not found
 
 
). Therefore
the previously observed variability is unlikely to be related to S190814bv.

Thank you to CSIRO staff for supporting these observations.
