Supernova 2006el and 2006dn in UGC 12188

This page is devoted to information on supernova 2006el and 2006dn in UGC 12188.   Basic information on these SN, including the last reported brightness, on this Supernova can be found on the main page.  Information on the original web pages for many of these images can be found on the updates and links web pages.

2006dn was discovered by Lick Observatory Supernova Search (USA) on 2006/07/05.45.   LOSS does follow up observations on all of their supernova discoveries (which they do not publish BTW), and on 2006/08/25.28 they discovered Supernova 2006el.

The host galaxy for both of these supernovae is UGC 12188.   Double supernovae are rare, but they happen about once a year these days.   These supernovae are fairly faint, so look at them while you can.   We have a DSS Photometry reference image made by Odd Trondal.  Icons generated from the discovery images.   This supernova is in the Constellation Lacerta.

Light curves and Spectra:
• CfA spectrum of 2006el September 2, 2006 UT, FLWO 1.5m spectrum shows this Type IIb supernova (originally classified by us as a peculiar type-Ib) around maximum light, compared with the peculiar type-Ib SN 2005bf at -4 days.
• CfA spectrum of 2006el September 17, 2006 UT, FLWO 1.5m spectrum shows that SN 2006el is indeed a type-IIb event, based on the comparison with SN 2006T.
• SNWeb 2006dn Measurements and 2006dn light curve.
• SNWeb 2006el Measurements and 2006el light curve.
