[vsnet-alert 22259] Re: [vsnet-outburst 22298] V631 Her: long outburst (supermaximum?)

Wed Jun 27 04:30:34 JST 2018

Hi Patrick,

Most recent observations from CBA Extremadura (0.40m f/5.1 telescope):

HERV631 20180625.992 17.3 CV VMT

The object is too faint to attempt decent photometry, considering also the strong moonlight right now.

Best regards

CRTS detection. This is probably the first secure astrometry of this dwarf nova. Only two outbursts in the CRTS data.
