In vsnet-obs.1165, M.Kishiro questions if HS1804+6753 might be currently
in outburst, based on his observation of 950917.472 . My own first two
observations of this star do seem to indicate that it has brightened
quite significantly in the past two days:
date mag
------ -----
HS1804+6753 950916.0299 14.4
950918.0493 13.2
Having carefully examined the surrounding GSC stars, I would also like to
suggest to observers that the following stars appear to form a reasonably
consistant, visually acceptable sequence for use in future observations
until a PEP(V) or CCD(V) magnitude sequence becomes available:
(2000.0) 180224.8 +675035.7 GSC mag 13.3
180337.5 +675701.7 12.1
180347.7 +674923.2 12.9
(180414.1 +675412.1 HS1804+6753)
180425.2 +675135.1 14.5
180436.4 +675500.5 15.1
180500.3 +674342.5 13.6
