Here's a good web page for information about supernovae:
http://www.supernovae.net/isn.htm
...and the latest information about SN2009dd in NGC4088, including an
image which has the location of the SNe marked.

and the discovery image from the Italian CROSS (Cortina Astronomical
Assn. remote observatory supernovae search) team, taken on 04-13-09:

(Note: as usual, you won't observe the tick marks in the sky, haha)
SN2009dd is a type II, at approximately magnitude 13.5, and the galaxy
is about 10.5.
This galaxy also had a previous SNe, SN1991G.
The nearby field stars are all approximately magnitude 15 - 17, which
can be noted on this deep photometric reference image of NGC408 (also
showing SN1991G):

There are some foreground stars superposed on the image of the galaxy,
but the current SNe is evidently close in, next to the core of the galaxy.
Have Fun!
