Supernova 2009nr in UGC 8255

Hi All,

I've just learned from Brian Skiff via the AMASTRO mailing list that CBET circular 2111 announces a relatively bright supernova associated with the Virgo galaxy MCG +2-34-2. To quote Brian:

" ... CBET 2111 reports the discovery of a moderately bright
supernova near UGC 8255. This is a mag 14 galaxy of low surface
brightness. The galaxy is at: 13 10 56.5 +11 28 39 (J2000),
while the supernova is about an arcminute to the northeast at:
13 10 59.0 +11 29 29 (J2000). Reported magnitudes are about 14.0,
fully as bright as the galaxy itself. This is very much a pre-dawn
object, and the Moon is not far away at the moment."

Though it is a faintish galaxy, the location isn't too hard to pick up. The fact that it is a relatively low surface-brightness galaxy coupled with the supernova being located in the galaxy's outer halo and reasonably bright means a good 10-12" should pick it up.

Have to wait till about 2.30am ESDST for it to get high enough. MCG +2-34-2 is located 2.25 deg ENE of 3rd magnitude Epsilon Virginis (Vindemiatrix). There is a nice bright 6th magnitude M-type marker star in the same field as the galaxy, about 20 arc-mins to the galaxy's NE.

FYI.


Best
