In a further e-mail of August 22, he advised that a confirmation image had been obtained Aug 22. The new object is located at: RA 17h 19m 35.15s DEC +86 44' 30.4" (2000), which is approximately 4.4"E and 12.2"N of the centre of the host galaxy. Nothing is present at this position on Tom's images of 2008 Feb 10 and 2009 Aug 9 (limiting magnitude 19.5) nor on the Digitised Sky Survey Plates from 1996-08-05 (limiting red mag 21.0), and 1998-05-31 (limiting blue mag 20.5). The object was designated Supernova 2009ij and announced on CBET 1922. Congratulations to Tom on the discovery of his 124th supernova. SUPERNOVA 2009ih IN MCG +07-33-12 Guy Hurst, Basingstoke, reports confirmation of this earlier discovery by Tom Boles (c/f TA E-Circular 2575) remotely using the Bradford Robotic Telescope. On 2009 Aug 23 (01h17mUT) the magnitude was estimated to be 17.2 by eye comparison with A2 stars converted to V, as photometry proved too difficult due to the object's closely proximity to the host galaxy nucleus.

Filippenko report the independent LOSS discovery of SN 2009hi providing position end figures 56s.26, 29".8. Guy Hurst, using the BRT, reports photometry on 2009 Aug 2 (04h34mUT) giving a magnitude of 18.6 (A2 converted to V). Guy M Hurst
