Dear colleagues!
I would like to send you observations of a new variable star
(Brh V124), which I have discovered in a systematic CCD-based
search for new variables.
In each observing run typically 400 images are taken of several survey
fields.
The frames are processed automatically.
Instruments:
CCD-camera: Starlight Xpress SX (unfiltered)
Telescope: Celestron-8 (20 cm Schmidt-Cassegrain)
New variable star:
new Brh V124 212544.1 +160211.1 (J2000) 12.2-14.2 (CCD)
comments:
Brh V124: GSC 1663 403
The comparison star is GSC 1663 145 (12.4 mag),
which has been checked for constant brightness.
The USNO-B1.0 magnitudes (b1mag: 14.56, b2mag: 16.89,
r1mag: 11.42, r2mag: 10.95) and the following observations
suggest a long period variable with a relatively high amplitude,
maybe a Mira variable.
