RECENT SUPERNOVAE

The following UK/Ireland discoveries reported in recent E-circulars 
have received formal designations:

SN2012eg in NGC 1213 = PSN J03091697+3838207 (E2849) discovered by Tom 
Boles, Coddenham, England. Type-IIP supernova similar to SN 2005cs 
about one month after explosion (CBET 3207).

SN2012ej in IC 2166 = PSN J06265101+5905026 (E2852) discovered by Dave 
Grennan, Raheny Observatory, Dublin, Ireland. Type-Ic somewhat past 
maximum (CBET 3211).


CLOSE APPROACH OF NEO 2012 QG42

Richard Miles (BAA) reports that this relatively large NEO will be 
observable for northern hemisphere observers between September 4-14 
during which time it will attain magnitude 15.0 or brighter.  The 
object probably measures between 200-500 m across and is a current 
radar target. It will be brightest around September 10-12 when it will 
reach V=13.6 on average. It passes closest to us around 05h UT on 
September 14 at a range of about 7.4 lunar-distances (0.019 AU).

2012 QG42 is a potentially hazardous asteroid (PHA) and is unusual in 
that it passes very close to the opposition point on September 7. The 
circumstances of this close approach therefore makes this object a good 
target for photometry (using a V, R or r' filter if possible) as well 
as other physical studies.

COMET P/2012 P1 = P/2006 U5 (CHRISTENSEN)

CBET 3214 reports the recovery of comet P/2006 U5 by Artyom Novichonok 
and Otabek Burhonov using the 1.5-m f/8 reflector at Majdanak 
observatory in Uzbekistan.  the comet showed a small coma and a short 
tail 5" long in p.a. 242 deg on Aug. 15. It is currently a 21st mag 
object in Pisces and will be for quite some time.


COMET C/2012 Q1 (LEMMON)

CBET 3215 reports the discovery of this comet by Richard Kowalski using 
the Mount Lemmon 1.5-m reflector. This object was initially posted on 
the NEOCP webpage and its cometary nature was also noted by other 
observers. Ar present the comet is a 19th mag object in Pegasus.
