[vsnet-outburst 21629] Re: [vsnet-alert 21712] PNV J06501960+3002449: new transient (12.6 mag) in Gemini

[FIDRICH Robert]

PNV J06501960+3002449 as clearly visible on my prediscovery DSLR images
made at 2017. dec. 17.102UT.
Visual estimates from the DSLR image sugges that PNV J06501960+3002449 was
already in outburst near 13.0TG. Proper photometry will be done later.
