Hi Robert,

There is a V ~21 red source (likely a red dwarf) 1" away (19 27 48.04 +19 39 
32.7) from your position: 2MASS J19274805+1939325 = WISE J192748.06+193932.3 
= IPHAS J192748.04+193932.7 = UGPS J192748.04+193932.5.

It would be a very large flare (~8 mag.) but not unprecendented.

Cheers,
Sebastian

Confirmationneeded

Dear Friends,

It seems there is nothing unsual object on the CCD images made by Vikrant
Kumar Agnihotri
<https://www.facebook.com/vikrantkumar.agnihotri?fref=gc&dti=175919765800176&hc_location=ufi>
using i', z' and 565RB GCE filters :(

Maybe this 'object was an artifact? Or a fast flare?

Clear skies,

Robert
