[vsnet-id 745] Ids of several red variables in Per and Psc

["Ondrej Pejcha" <opejcha@volny.cz>]

Dear colleagues,

I have tried to work a little bit with astrometry. I
selected several faint red variables with inaccurate
positions in GCVS in Per, Psc and Tri and observed them with
CCD. Firstly, V and I images were taken to search for red
objects. Then, second epoch images (this time only I band)
were acquired to search for variability (time baseline 77
days).

Positions were measured using Astrometrica and USNO A2.0.
Here are the results:

name      delta_mag RA(J2000)   err_ra  Dec(J2000)  err_de
AX Psc    0.14      01 12 13.49 0.29    +32 47 11.3 0.39
EP Per    1.70      02 55 11.58 0.24    +54 25 46.7 0.26
QR Per    0.36      03 00 48.44 0.35    +56 14 10.0 0.37
V363 Per  0.19      02 41 07.85 0.25    +55 12 59.6 0.26

So the following identifications can be made with respect to
GSC:
AX Psc = GSC 2295:548
QR Per = GSC 3705:101
EP Per and V363 Per are not in GSC.

Besides, VY Tri and WX Tri were also observed. Concerning VY
Tri, no red or obviously variable object was detected in the
field. I forgot to take V band image of WX Tri, however WX
Tri is probably GSC 2318:452, which changed its brightness
by about 0.07 mag (not very much) on my images.

Best regards,

Ondrej Pejcha
