My discovery of Supernova 2006Au in the galaxy UGC 11057
Lots of gold (Au) was probably produced. Discovery date Mar. 7.202 2006. Supernova is at Mag 16.5

My discovery of Supernova 1999cb in the galaxy Markarian 881.
The supernova is at mag.16.1 and 15" SW of the galaxy.
Date : 4. April 1999 Time : 02:42 Exp.time 100 sec. ST-4 CCD and 0.61m f/2.2 telescope.
Nice weather, no wind. Telescope was tracking optimal.

The galaxy has a red shift of Z = 0.02881 ( RV = 8637 km/s ),
it is probably a Type Ia supernova with peak magnitude 15.7
Using Hubble constant Ho = 72(km/s) / Mpc we get a
distance = V / Ho Mpc = V / Ho * 3.2616*10^6 l.y. = 8637 / 72 * 3.2616*10^6 = 390 millions light years.
