---------------------
Additional information on this Nova
recently requested by T.Kato. Nova is seen in a bright decay phase
in R frame of STScI digitized survey on 1997 April 8, what may be
the cause of its presence in GSC. I have found the images of Nova
on our glass copies of Palomar Sky Survey from the plates taken
on 1958 April 18/19. The star has the magnitude of about B=16.5 and
very blue colour relative nearby stars. STScI and PSS images suggest
that this is the same star. Pre-nova is seen on a single accidental
plate of Sternberg collection taken in 1974: JD 2442199.5, B=16.2.
The light curve shows, that Nova has reached now its pre-outburst
brightness. Being so bright in quescent state it is an excellent
object for investigations.
