ASTRO: SN 2008ax in Galaxy NGC 4490

A 15:5:5:10 minute LRGB exposure with STL 1301E camera thru a 20-inch F/8 RC
Cass. Seeing was poor, but the sky was pretty transparent.

The image was centered around 4:30 UT on March 30, 2008. I measured the SN
as red = 13.3 mag and blue = 14.5 magnitude.

Still working on data, so no link to this yet.

The pro's have been changing their minds on what the classification type is
for SN 2008ax. The current thinking is that it is a Type Ib. SNs are
classified according to their spectra, not what the actual physical object
is. I've attached a chart that shows what most astronomers are thinking
about type and related object.

Looks like it may be slightly brighter in your shot than mine. Seems
larger in relation to the star just beyond the galaxy anyway.

Nothing but snow and clouds here.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Great picture George. I was wondering if you could ignore that one ;-)

Stefan,

I love stuff that blows up!

I'm going to have to get back to SN hunting!
