New variable star discovered on Stardial-CCD-images (HassfortherV45):
2000 184622.0 -050234.7 HassfortherV45 8.5-<10.5I M P=480d
HassfortherV45
(2000) 18h46m22.0 -05 2.5779
= IRAS 18436-0505
Checking 211 Stardial-images from 1996 to 2000 showed
IRAS 18436-0505 to be a Mira star.
The period is probably around 480 days judging from the lightcurve
with Maxima around 2450960 and 2451440(:).
Differential Photometry was done with MIRA AP 6.03 with respect to
GSC 5129-29 (V=8.72, B-V=1.2).
There is a nearby star (GSC 5122 886) which contaminates the
measurements when V45 is weak.
