BLAZAR PKS 0507+179
D. Denisenko et. al., Moscow State University, reports on The 
Astronomer's Telegram 4424 that the MASTER-Kislovodsk auto-detection 
system discovered an optical transient source at:
RA 05h 10m 02.32s DEC +18 00' 41.5" (2000)
on 2012-09-25.0768UT. The OT unfiltered magnitude is 16.2 (limit 19.0m).

The OT is found identical to QSO B0507+179 = PKS 0507+179 = NVSS
J051002+180041 = USNO-B1.0 1080-0080773 (catalogue magnitude R=19.09).

They have 14 past positive observations of this object in 
MASTER-Kislovodsk database, the range of variability is from 18.7 to 
16.6 mag (unfiltered with the Red zero point). The current magnitude is 
the brightest ever observed by all MASTER telescopes for this object 
since 2009 Jan 22.

The discovery and reference images are available at:

NO NEW OBJECT IN HYADES
Further to the report by Ian Shelton on TA E-Circular 2864, he has now 
reported there is no new object and that the pictures apparently showed 
a ghost image of a bright star. Thank you for all who sent in images 
promptly which confirm these latest findings.
