Following Ron Arbour’s recent supernova discovery, Tom Boles has made two more of his own, bringing his total to 110. The first, on Feb 7.005UT, was in galaxy NGC 4141, a mag 14(p) galaxy close to delta Ursae Majoris. The supernova was discovered using a 35cm C14 Schmidt-Cassegrain and Apogee AP7 CCD camera. It was at magnitude 17.6, has been designated SN 2008X. The discovery was announced on CBET 1239 and 1242, and TA circular E2419. Tom’s position for the supernova at RA 12h 09m 48.33s and Dec. +58o 51’01.6” puts it 7.6” east and 4.6” north of the galaxy centre. The supernova has been determined as a type IIp.

Two nights later on February 9 Tom confirmed that discoveries often come in twos when he discovered 2008af in galaxy UGC 9640, a magnitude 14(p) galaxy in Bootes. Announced on CBET 1248 and TA circular E2420, the supernova lies at RA 14h 59m 28.51s and Dec. +16o 39’12.2” putting it approximately 12.4” east and 29.6” north of the galaxy centre. This discovery was made with the same equipment set up as SN 2008X. At the time of writing the type has not been determined. Tom’s discovery images, with the supernovae marked, are shown below.
