Hi all,
A couple of days ago a message was posted to the local NZAstro group alerting us of a possible SuperNova in galaxy NGC4945.:cool:
So last night I was determined to photograph it. I dodged clouds for about 3hrs and finally gave up...:cloudy:
Ended up with a single 4min shot for my efforts.! Still the SN was there as predicted. :cool2:
When compared to a 4945 image I did last year it is easily detectable.
They are predicting the SN to get to Mag10. Currently it is about Mag12. Might be worth keeping an eye on.
Cheers

Here is some more detailed info we got from a local...
The following note from IAUC 8482. Mati Morel (who does charts for variable
star observers) notes that NGC 4945 is only six times more distant than M31.
Hence the SN could reach magnitude 10.

POSSIBLE SUPERNOVA IN NGC 4945
C. Jacques and E. Pimentel, Belo Horizonte, Brazil, report
their discovery of an apparent supernova (mag 12.8) on unfiltered
CCD images taken on Feb. 8.22 and 10.23 UT with a 0.30-m Schmidt-
Cassegrain reflector in the course of the CEAMIG/REA Supernovae
Search. The new object is located at R.A. = 13h04m44s.06, Decl. =
-49o33'59".8 (equinox 2000.0), which is 407" west and 351" south of
the center of NGC 4945, but which also lies in a rather rich area
of foreground Milky Way stars in Centaurus. Nothing in visible on
a CCD image taken by Jacques on 2004 June 20.93 (limiting mag 18.5)
or on a red Digitized Sky Survey plate from 1976.

That is very cool. & shows that there is more to astro imaging than making pretty pictures.
