I would like to send you observations of a new variable star (Brh V138), which I have discovered in a systematic CCD-based
search for new variables. In each observing run typically 600 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 V138 20 02 26.5 -04 46 35.4 (J2000) 13.1-14.1 (CCD)
comments:
Brh V138: GSC 5168 2029
The comparison star is GSC 5168 916 (12.7 mag),
which has been checked for constant brightness.
The following observations suggest an EA variable, period still unknown.
Further ASAS3 observations are available at
http://www.astrouw.edu.pl/~gp/asas/asas.html
which confirm the variablity and the EA type.

With the minima observed by ASAS3, the period of this star is most
likely 1.6851 days.
The ASAS3 data possibly also show a very shallow secondary eclipse near
phase 0.5, but this needs confirmation.

Yes, Patrick's period is right.
I found the following elements:
Min I = HJD 2452087.723 + 1.68502 x E
V= 12.06 - 13.18
Secondary eclipse V= 12.25
Bernhard unfiltered observations were normalized to the ASAS-3 V magnitude
for the graph at:

A very nice EA star.
Regards,
Sebastian.
