 > Ian Shelton (Mount Allison University & U. Toronto) wrote in
 > Astronomer's Telegram #4513 that a possible 6th magnitude transient with
 > very red color was detected in a DSLR image of the the field of the
 > Hyades on 2012 October 22.4361 (JD 2456222.9361). Coordinates given for
 > the transient are the following (J2000):
 >
 > RA: 04 23 29 , Dec: +17 58 29
 >
 > No additional information about the exposure, filters, or other imaging
 > techniques used were given, and only a single image was presented in the
 > Telegram. We have independently checked VSX to ensure that there is no
 > known variable star within 10 arcminutes of this position, and the Minor
 > Planet Center's MPChecker utility (available at
 > http://scully.cfa.harvard.edu/cgi-bin/checkmp.cgi ) yields no minor
 > planets coincident with that position and time.
 >
 > This is a very tentative report, and confirming observations are 
required.
 > If the transient is confirmed, followup observations -- including
 > spectroscopy -- are strongly encouraged.
