My supernova discoveries:

 

SN2009gh in  MCG +12-18-2  type IIP CBET 1850

Discovery date June 17, 2009 - MCG +12-18-2 is a Sb spiral galaxy in eastern Draco. Spectra of this supernova were obtained with the F.L.Whipple Observatory 1.5 meter and MDM Observatory 2.4 meter telescopes.

 

SN2008ev in  UGC10155  type II CBET 1468

First supernova found with the Meade 16" OTA - discovery date August 9, 2008. The confirmation spectrum was obtained with the 2.5 meter Nordic Optical Telescope (NOT). UGC10155 is located in the constellation Corona Borealis close to the Hercules border.

 

 

SN2006sr in  UGC14  type 1a  IAUC8784

Discovery made on December 12, 2006. UGC14 sits inside the "Great Square of Pegasus". Spectroscopy was accomplished with the Lick Observatory 120 inch (Shane) Reflector. The telescope is located on Mount Hamilton, in California.

 

 

SN2006O in UGC633  type II  IAUC8662

Discovery made on January 22, 2006. UGC633 is located in the constellation Pisces. The spectrum of this supernova was obtained with the F.L.Whipple Observatory 1.5 meter telescope. The telescope is located on Mt. Hopkins near Amado, Arizona. CFA spectrum

 

 

SN2005bx in MCG +12-13-19  type IIn  IAUC8521

Discovery on April 26, 2005. MCG +12-13-19 is located in western Draco . SN2005bx was observed by the Chandra X-ray Observatory on July 30, 2005. At 45 feet long, Chandra is the largest satellite the shuttle has ever launched (Chandra trivia).  ATEL475

 

 

SN2005ay in NGC3938  type IIP  IAUC8500

Discovery made on the evening of March 27, 2005. NGC3938 is located just below the "Big Dipper" in Ursa Major. Spectra of this supernova were first obtained with the Calar Alto 2.2-m telescope (southern Spain) and the 200 inch Hale telescope at Palomar. SN2005ay was observed in ultraviolet light by the GALEX Space Telescope on April 2, 2005.   NUV-optical- IR composite image of NGC3938 and spectra of SN2005ay    ATEL448

SN2005ay was imaged by the Hubble Space Telescope on December 11, 2007.

 

 

Super Outburst of Luminous Blue Variable in NGC4656 IAUC8497

This LBV was discovered March 20, 2005. NGC4656 is located in constellation Canes Venatici. Classification of subluminous (peculiar) supernovae can sometimes be difficult. In some cases, these "low-power" exploding stars may actually be super-outburst events of Luminous Blue Variables and not true supernovae (SN1997bs, SN1999bw). The spectrum of this LBV was obtained with the Telescopio Nazionale Galileo (TNG) telescope located on the Canary Islands.

 

 

SN2004gx in UGC12663  type II  IAUC8459

This discovery was made on the evening of December 30, 2004 with the Meade 12" OTA, Paramount ME, and ST9XE combination. UGC12663 is located inside the "Great Square of Pegasus".

 

 

SN2003dw in UGC10548  type 1a  IAUC8124

My third discovery on April 26, 2003 was the first made with the Meade 12"OTA, Paramount ME mount and ST-9XE camera combination. UGC10548 is a barred spiral galaxy located in the constellation Draco. CFA spectrum

 

 

SN2003O in UGC2798  type II  IAUC8055

This discovery on January 18, 2003 was made with my 10" LX200 and ST9XE camera. The image is "noisy" because of a full moon rising. UGC2798 is located in the constellation Perseus.

 

 

SN2000cz in IC1535  type II  IAUC7470

My first discovery on July 24, 2000, was captured with a Meade 10" LX200 and ST-6 camera. Because of problems with the verification process, I did not receive credit for this discovery.
