[vsnet-alert 23910] Re: TCP J06073081-0101501: new transient (13.9 mag) in Orion

[Graeme Coates]

Sequence now in place on AAVSO VSX database - I have just uploaded my
observations from 2020-01-28 1936-2136UT into AAVSO and BAA databases
(before being clouded out...).

Observed with 350mm reflector with V filter from W Oxon, UK.
