More useful info on this eruptive star.  Remember, the contaminating star
will be of no importance whatever as long as the eruptive star remains
bright.  Good luck!

Following the posting on the Central Bureau's Transient Object
Confirmation Page about the transient in Peg we performed some
follow-up of this object remotely through a 0.25-m, f/3,4 reflector +
CCD, from GRAS Observatory (near Mayhill, NM).

On our images taken on May 25.3, 2011 we can confirm  the presence of
an optical counterpart with unfiltered CCD magnitude about 11.0
(USNO-B1.0 Catalogue reference stars) at coordinates:

R.A. = 21 09 50.46, Decl.= +13 48 39.6

(equinox 2000.0; USNO-B1.0 catalogue reference stars).

According to VIZIER there is a 18.82 R2 magnitude star at 0.0099
arcmin from the transient position (USNO- B1.0 1038-0586809).

Our confirming image of this transient and an animation showing a
comparison between our image and the archive POSS2/UKSTU plate (R
Filter - 1991):


With kind regards,
