[vsnet-outburst 24451] Re: [vsnet-alert 23796] ASASSN-19adk

Observations last night of asassn-19adk at CBA Kleinkaroo produced object
coordinates : 09 44 14.86  -63 39 13.0 vs UCAC2,
This is close to the ASASSN given position but the refered match to Gaia
DR2 5249821951350837888 as counterpart is probably incorrect based on
visual inspection.

Timeseries photometry were not done but are intended.
Image will be sent to VSNET .
