Hola everyone -

A more thorough reduction gives for Brown's new object in Sgr =


YYYYMMDD(UT)   mag  observer    Comments

20030919.1035   8.91    Liller  CCDV   +/- 0.05
20030919.1056   9.79    Liller  CCDB   +/- 0.15     ( B-V =3D 0.88 +/- 0.=
17 )


All observations through thin cirrus clouds.  Eight TYCHO stars used for
standards.

A grating spectrum with dispersion 7.8 A/pixel shows a prominent H-alpha
emission with a peak approximately 2.3 times brighter than the surroundin=
g
continuum.  The measured FWHM of this line is 550 km/sec.  A narrow P-Cyg=
ni
absorption appears to be present and shifted 590 km/sec towards the blue.=


Nothing is visible to mag 11.5 on a red film taken on Sept. 13.12 U.T.

There can be no doubt that this is a nova.  Congratulations Nick !

All the best to all,   Bill Liller
