New variable Star HassfortherV14

By blinking Stardial-images the star GSC 5133-2273 proofed to be variable.

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

Checking 206 Stardial-images from 1996 to 2000 showed GSC 5133 2273 to be a semiregular red variable star. The period may be in the order of 200 days, the amplitude about 0.8 mag. Here as an example the lightcurve of 1999 (in the other years the light curve was less clear). 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 of GSC 5133-2273 proofed the star to be variable with a 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)

The Stardial-project is one of the most fascinating aspects of the WEB, many thanks to Peter McCullough!!
The TASS-Database is a very valuable source to check and verify new findings. Many thanks to the TASS-people!!
