Dear Sirs,
Suspected variable star in Vulpecula:
I have found what seems to be an uncatalogued
variable star with large amplitude in Vulpecula,
at 19h09m49.1s, +22d00'18" (J2000). The red
magnitude range is at least 13.4-17.4. It could
be a Mira star, but I do not know anything about
the colour of the object.
The star could not be identified in GCVS, NSV,
USNO-A2.0, Dearborn, or IRAS.
The images available to me were as follows:
POSS-E Red, Plate XE392, Epoch 1950.456: rmag 17.4
POSS-II Red, Plate XP593, Epoch 1991.530: rmag 14.3
POSS-II RED, Plate XP524, Epoch 1992.422: rmag 13.4
Magnitudes were estimated from USNO-A2.0 red
magnitudes of nearby stars.
Comments and observations are appreciated.
Regards,
Hans Bengtsson,
Hisings Backa, Sweden
