Hi Ella Managed 3 x 15 min images from New Mexico. There's definately something there. Difficult to measure Mag/Position but here's what I got: RA 00 15 30.59 Dec 17 19 31.7 Mag 20.7 +/- 0.3 L 2012.6.28.404 Note there is something slightly west of the SN candidate at RA end 29.75 Dec end 28.9 - but something maybe already there from the DSS2 image. Attached are links to the FITS file and a jpg (post digital development) Best wishes Joe
