[vsnet-campaign 1359] HD 23873




>>>Apparently HD 23873 has faded by ~0.16 magnitude.  SIMBAD lists HD 23873
at V=6.606 with spectral class B9.5V.  The UBV catalog shows a range of 6.57
to 6.62 for this star.  More observations will be required to confirm the
fading of HD 23873.


Dear Doug and colleagues,

Last night I observed HD 23873 and it doesn't seem to be fainter....
My visual observation is:

HD023873     20030105.029     66      OSE

The raw result was 6.63. There are good comparison stars. See my chart at:
http://ar.geocities.com/varsao/Carta_BU_Tau.htm

Maybe the proximity of  HD 23872 (V= 7.5) has its influence in some of the
results??

On the other hand, from GCPD and Hipparcos photometry, the magnitude of 18
Tau (the "new"
comparison star) is V= 5.66.

Regards,
Sebastian.
