Hola everyone -
Last night, July 18.15 UT, through thin clouds, I was able to get a CCD
objective grating spectrogram of the possible nova in Ophiuchus. H-alpha
is present and strong in emission, some 12 times the intensity of the
surrounding continuum. Its FWHM = 1450 km/sec.
Here is what I have for the magnitudes:
object YYYYMMDD(UT) mag code comments
OPHnova2003 20030607.117 <11.1R LIL Red photographic*
OPHnova2003 20030623.132 10.4R LIL Red photographic*
OPHnova2003 20030714.985 11.1R LIL Red photographic*
OPHnova2003 20030718.114 11.29V LIL CCD through clouds, +/- 0.07 mag
OPHnova2003 20030718.116 12.13B LIL CCD through clouds, +/- 0.07 mag
Thus, the nova has a B-V of approximately +0.8.
All the best to all, Bill Liller
