[Bela1996@aol.com]

New variable star discovered on Stardial-CCD-images (HassfortherV41):

2000 185542.08 -012305.8 HassfortherV41 10.2-11.0v EB P=2.7814d(:)

HassfortherV41
(2000) 18h55m42.08  -01 23.097
= GSC 5115-0246    (10.06 SERC-V)
= Tycho 5115 00246 1
  (BT = 11.040, Error 0.047, VT = 10.372, Error 0.039, from Tycho-II)

Checking 215 images from 1996 to 2000 showed GSC 5115-0246 to be
an eclipsing binary (EB-subtype). No sure period could so far be
established due to strong aliases. 
Differential Photometry was done with MIRA AP 6.03 with respect
to GSC 5115-3813 and GSC 5115-0404.

One possible period is 2.7814d.
Amplitude 0.8mag (in the System of Stardial: red-filtered KAF0400)

A check of the available TASS-measurements proofed
the star to be variable, with no new insights.
