[vsnet-campaign-news 127] Nova Oph 2002 = HadV105, spectroscopy and further astrometry
The nova (HadV105) has been spectroscopically confirmed to be an Fe-II
class nova:
(vsnet-discovery-nova 35)
A. Retter, S. O'Toole, University of Sydney; R. Stathakis, J. Pogson,
AAO; T. Naylor, Exeter University, report:
We observed the possible nova Oph 2002=HadV105 (IAUC 7808) with the
3.9-m AAT telescope (+RGO) in January 26, 18:30 UT. Preliminary analysis
of the medium resolution spectra (400-700nm) shows that they are
dominated by strong emission lines and possibly weak P-Cygni profiles.
The strongest lines are H-alpha, H-beta and Fe II multiplets 42, 74, 48,
49, 55 etc. The FWZI of the H-alpha and H-beta lines is 2350+/-100 km/s.
The object is, therefore, very likely a classical nova than belongs to
the Fe II class, caught at the early decline phase.
Astrometry by K. Kadota:
2002 01 27.840 UT (4 frames)
R.A. = 17h37m34s.36 Decl. = -16o23'18".4 (equinox 2000.0)
12 reference stars from GSC-ACT.
Mean residuals: 0.14" in R.A., 0.15" in Decl.
0.18-m f/5.5 reflector.

VSNET (Variable Star Network) is an international variable star observing
network, covering various areas of novae, supernovae, cataclysmic variables
(CVs), X-ray transients, and other classical eruptive, pulsating, and
eclipsing variables. VSNET is one of invited contributing organizations
to the SkyPub AstroAlert system.

CCD observations of such targets are a relatively easy task for a 20-40cm
telescope; simply take as many CCD frames (with exposure times 10-30 sec)
as possible, spanning several hours per night. The only requirements are
the weather and your patience! If you need more help on the observing
technique, please feel free to ask on the vsnet-campaign list.
We would sincerely appreciate volunteers who would join the VSNET
Collaboration team to study the wonders of these exotic variable stars.
