Possible SN finds
« on: June 19, 2013, 06:28:50 pm »
I found these two images


1237654604249104401



1237654604249104407



SIMBAD says SN 2012cw    58.48    SN    10 13 47.95    +03 26 02.6   for the first one and
SN 2012cw    31.30    SN    10 13 47.95    +03 26 02.6 for the second

Are both Supernovae?

Now that's from Hubble and there isn't much to pin it down exaxtly, just some NED info.
Here's the Hubble picture:

Here's a really nice, visible one.





1237658299527594039

And it's name: SN 2002au

Quote from: SIMBAD

Basic data : SN 2002au -- SuperNova



Also we learn that it's a type Ia SN and that it's redshift is z=0.018565 .

Now with a little help from Wolfram Alpha we find out that that's about 257 million ly from us (or 78.6 Mpc)
UGC 5100 on the other hand has a z=0.01828 which means that it is 253 million ly from us (77.4 Mpc)
Doesn't that mean that it's behind the galaxy?

Unfortunately this one isn't visible anymore.



It's reference number is 1237679504330391634.

From SIMBAD we learn that it's name is SN 2008eg, and that it is an Ia type.

Quote from: SIMBAD
Basic data : SN 2008eg -- SuperNova



SN.Ia

There is no available redshift, but the redshift of UGC 01324 is z=0.033657

Quote from: NED
CROSS-IDENTIFICATIONS for SN 2008eg
Object Names   Type   Object Names   Type
SN 2008eg   SN   UGC 01324:SN 2008eg   SN

So we can assume that the Sn is within the galaxy and has therefor a similar z.

Here's an Astrosurf image, which is a little better:

This one's obviously not visible as it was observed in 1958.

SN1958B
As it is obvious that your targets on SDSS and Simbad are different, you'd better post only SDSS img on coords of SN.
You have to read carefully the data after pressing the Ned button on explore: the results are
"Object list is sorted on Distance to search center"

Object 1237678617971916821 is at a separation of 0.322 arcmin from the SN1958: it missed it by a great offset!

Do you know you could add a mark on pics:


For a transient event it'd good also to give the date of discovery and the date of the SDSS pic for avoiding confusion by the reader.
Thanks
