[vsnet-campaign-news 138] Possible Nova in the LMC region (Liller)
====================================================================
Possible Nova in the LMC region (Liller)
====================================================================
We have received the following report from W. Liller. There is no
registered variable star, nor infrared source (2MASS sources in this
field is already released). The position is in the LMC area.
If the object is confirmed to be a genuine nova in the LMC,
the magnitude of 10.5 make the object a relatively bright nova in the LMC
(may fade rapidly). Further observations are strongly encouraged.
In case the object is confirmed to be a nova in the LMC, the VSNET
reporting name is LMCnova2002. We tentatively use this name in our
upcoming circulars.
Regards,
Taichi Kato

Subject: Nova susp.
Hola Everyone -
Please check to see if there is a star at (2000) RA = 5h 36.8m, Dec -71d
36'. On two photos taken at March 3.0651 and March 3.0677, its magnitude
with Tech Pan film, no filter, was 10.5. On two photos taken at Feb.
27.0643 and Feb 27.0641, it was about mag 12.5 (through cirrus and with
full moon). On two photos taken Feb 21.0620 and Feb 21.0641, nothing was
seen down to about mag 15.
Tonight looks good here; I should be able to get a spectrum and a better
position.
All the best to all, Bill Liller

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.
