Hola, Everyone -

 At UT June 21.660, using nearby GSC 7382 837 as a standard and adopting 
V = 9.87, B-V = +0.44, I measured Haseda's nova-like variable with a CCD
to have a broadband V magnitude of 10.68 +/- 0.03.  A low dispersion
objective prism spectrogram recorded with the CCD shows a very intense
red line, presumably H-alpha (but remember V445 Pup !), that is approximately
5 times the brightness of the surrounding continuum.  H-beta (?) is weakly
present indicating that the star is substantially reddened.

Congratulations Haseda-sen for his discovery !                  Cheers,

Bill Liller
