Dear Taichi and nova enthousiasts,
If the located star is indeed the progenitor of the brightened object then
its presumed nova nature is improbable.
I still believe (and might have mentioned it earlier) that the Pup-Pyx-Vel
region must be one of the most under explored MW region in the sky and quite a
number of CVs might still be discovered there. This Nova? Pup 00 might be one of
them...
Regards,
Berto
PS I didn't read e-mail since 24/12/00 and found quite some interesting
findings in my e-box. VSNET is doing a great info job!
We have to keep watch on TV Col. Could it be in a transition stage?
This is an exciting hobby!

So, > it could be interesting to know if the star reported by Dr. Kato comes from > a different USNO catalogue. Maybe these stars are the same. These stars are the same. I used USNO A1.0. If we adopt the USNO A2.0 magnitudes, the V-J color is even more bluer (closer to a slightly reddened cataclysmic variable). I wonder how accurate A2.0 photometric calibration in this field. Regards, Taichi Kato PS. If this object is indeed a nova (I suspect so...), the proginitor is one of the brightest ones in the recent dacades. |
