On Nova Oph 1998
The new astrometry by Hanzl (IAUC 6943) brings the nova closer (~1 arcsec)
to the nearest USNO star:
USNO0675.13305963 173159.788 -191355.04 (2000.0) 16.8 18.0
SGRnova1998 173159.79 -191356.0 (2000.0)
If the identification of the nova with this USNO star is proven, the
outburst amplitude may be rather small for such a fast nova (of course,
the value depending on the actual outburst maximum). Further assuming the
association with the ROSAT source, the previous X-ray detection may be the
result of earlier nuclear burning event, which may be explained by a recurrent
nova phenomenon. An extensive search for plate archives would be meaningful.
