[vsnet-alert 24472] asassn-20jc: large amplitude outburst

[Berto Monard astroberto13m@gmail.com via vsnet-alert]

Unfiltered CCD observations at CBA KKO over a duration of 0.2d show
ASASSN-20jc OT around magn 13.0CR, more than 2 mag brighter than the
discovery magnitude. The outburst magnitude therefore  >7mag.
Possibly a nova or alternatively another ugwz type CV.

The observations show a gradual fade with a non-cyclic modulation.
Astrometry vs UCAC2 gave a position (2000): 15 08 10.13  -09 13 04.6 with
uncertainties 0.02 and 0.1 for RA and Decl respectively.
