[vsnet-campaign-news 82] AstroAlert: Possible Nova by Haseda

[Taichi Kato <tkato>]

      ****************************************************************
                 Possible Nova by Katsumi Haseda
              Near the Constellation Border of Sco-Sgr
      ****************************************************************

   Katsumi Haseda (Aichi, Japan) reports the discovery of a new variable
star, which is apparently a nova or a variable star undergoing a nova-like
eruption.  The position (accuracy 0".5) of the object was measured as
follows by K. Kadota from the discovery image by Haseda.  The object is
located close to the Sco-Sgr border.

   17h 57m 06s.98  (J2000.0)
   -32o 23' 05".0

   Kadota also comments that there was no object brighter than mag 14
on a CCD image taken on 2000 Feb. 24.842 UT.

   There is no known variable star at this position.  A search on
2MASS and MSX5C catalogs has not revealed any likely counterpart.

   Spectroscopic confirmation, as well as multicolor photometry, is very
strongly encouraged.

   The information has been sent to the CBAT (Central Bureau for Astronomical
Telegrams).  We are going to prepare a WWW page containing the information
of this possible nova.  Please watch the URL below.  Urgent information will
be distributed via vsnet-alert mailing list.

   We have been undertaking on photometric campaigns on several super-
outbursting dwarf novae and peculiar variable stars.  News and call for
observations on these objects will be issued on our regular weekly
"News from VSNET" bulletins.  Those who immediately need information
should make an access to the VSNET website, and click on VSNET campaign
list.

  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.
To join the VSNET campaign collaborative list, send an e-mail to

         vsnet-adm@kusastro.kyoto-u.ac.jp (VSNET administrator)

with a line "SUBSCRIBE vsnet-campaign." or your comment to join the
collaboration team.
