New variable star discovered on Stardial-CCD-images (HassfortherV16)

2000 190711.50 -041001.0 HassfortherV16 10.2-<12.0I M 2450700+300

HassfortherV16
(2000) 19h07m11.50  -04 10.017
= IRAS 19045-0414

Checking 206 Stardial-images from 1996 to 2000 showed
IRAS 19045-0414 to be a Mira star. The period is about 300 days
and the amplitude greater than 2 mag in I.
The star is too faint to be measured on the stardial-images with MIRA,
but there are clear Maxima around 2450700, 2451000 and 2450310.

A check of the available TASS-measurements proofed the star
(TASS J190711.5-041004) to be variable and the Maxima
around 50700 and 51000.
The USNO-A2.0 gives R=13.9 and B=17.6 for this star (0825-14497900).
