[vsnet-newvar 467] New variable star GSC 5133 2273 (=HassfortherV14)

[Bela1996@aol.com]

New variable star discovered on Stardial-CCD-images (HassfortherV14):

2000 191233.24 -030835.8 HassfortherV14 9.8-10.6I SR 200d:

HassfortherV14
(2000) 19h12m33.235 -03 08.5968
= GSC 5133 2273
= IRAS 19099-0313

Checking 206 images from 1996 to 2000 showed GSC 5133 2273 to be
a red semiregular variable star. The period may be in the order
of 200 days. The amplitude reach 0.8 mag in the Stardial-System:
red-filtered KAF0400).
Differential Photometry was done with MIRA AP 6.03 with respect
to GSC 5133 1535 (= Hipp 94300).
The star ist very faint on the stardial-images, therefore the
internal error is rather big.

A check of the available TASS-measurements proofed the star to be
variable with small amplitude (about 0.3 mag in I).
Judging from the TASS-Photometry the star is very red:
V = 13.94 (12 measurements)
I =  9.39 (37 measurements)
