Ivanov (Irkutsk State University) report on behalf of the large MASTER collaboration (http://observ.pereplet.ru/): MASTER robotic network of 0.40-m f/2.5 twin telescopes equipped with identical 4Kx4K CCDs has observed the area of UGC 3528 four times in the last two months on the following dates: 2012 Aug. 20.773; Sep. 30.815; Oct. 10.843 UT (60-sec unfiltered exposures with MASTER-Amur) and Oct. 21.903 UT (180-sec exposure with MASTER-Tunka). Nothing is visible at the position of PSN J06561339+8404502 to the limiting magnitudes 18.2-18.7. Comparison of four MASTER images (scale 1.84"/pixel, 6'x6' crop, 200% zoom) is posted at this URL: http://master.sai.msu.ru/static/OT/UGC3528-MASTER-anim.gif

This object was observed by Raffaele Belligoli from Monte Baldo Observatory, Ferrara di Monte Baldo VR, Italy and confirmed by Raffaele Belligoli and Flavio Castellani on next night. The objiect was detectable on 21.9034 in a couple of images of 30sec each, taken by the 0.4m f.8 Ritchey-Chr├ętien telescope of the observatory. On 2012/10/23.9486 a second image of the field was taken; the magnitude of the object arise to 16.6. (Two images of 30s each and same instrumens). On 2012/10/24.7280 a third image was taken, by the observatory. This is the sum of three images of 30s each. The PSN is clearly observable near che nucleos of the galaxy (4.7"E and 5.8" N) and the magn. is 16.4 unfiltered. Astrometric position of the object is RA 06h 56m 13.39s +84┬░ 04' 50.2"

D. Denisenko, E. Gorbovskoy, V. Lipunov (SAI MSU), A. Parkhomenko, A. Tlatov, D. Dormidontov, V. Senik (Kislovodsk solar station of the Pulkovo observatory) report on behalf of the MASTER Net: PSN J06561339+8404502 in UGC 3528 is confirmed on two images (180-sec unfiltered exposures) obtained by MASTER-Kislovodsk telescope (0.40-m f/2.5 reflector + 4Kx4K CCD) on 2012 Oct. 25 at 20:29:33 and 20:33:11 UT. Position end figures from the sum of two images are: 13s.37, 49".4, unfiltered magnitude on 2012 Oct. 25.856 UT is 16.0+/-0.1. Supernova was not visible on three survey images obtained by the same telescope on 2012 Oct. 19.72 UT to the limiting magnitude of 18.3. Comparison of pre-outburst and post-outburst images is posted at this URL: http://master.sai.msu.ru/static/OT/PSNJ065613+840450-MASTER-Kislovodsk.jpg
