[vsnet-chat 4193] NSV 504

["Sebastian Otero" <varsao@fullzero.com.ar>]

Dear colleagues:
                        While checking out data for stars in our brand new
LIADA Observing Program, I realized some weird things about NSV 504.
The NSV lists it as a probably E type with a photographic range 6.5 - 7.8p

Well, 6.50 is actually the V magnitude for this star and not the "p"
magnitude.

The B-V color index is 1.348, or 1.3: exactly the difference between maximum
and minimum in the GCVS range.

So 7.8 p is okay. 7.8 is the photographic (blue) magnitud of (former?) NSV
504.

So both measurements are **PROBABLY** the same value ("maximum") but in
different bandpasses.

Original discovery papers should be checked.  (Hi, John!!!  :-))

Hipparcos photometry doesn't show any trace of variability.



Regards,
Sebastian.
