Vladimir Lipunov reports the discovery by Sergey Shurpakov of a possible supernova with unfiltered magnitude 16.9 on the survey images (180-s exposures, limiting magnitude 17.9m) obtained by MASTER-Amur robotic telescope (0.40-m f/2.5 reflector + 4Kx4K CCD) on 2014 Aug. 29.544 UT. The new object is located at the following position (J2000.0): R.A. = 22h15m26s.55, Decl. = -10o28'34".6 which is 7" east and 6" north of the center of dwarf irregular galaxy PGC 68414 = WHI B2212-10. D. Denisenko and E. Gorbovskoy report that nothing is present at this position on the images taken by the identical MASTER-Kislovodsk telescope on 2014 July 04.920 UT to the unfiltered magnitude limit 17.9. The discovery and reference images by MASTER are available at http://master.sai.msu.ru/static/OT/221526.55-102834.6.jpg with the color-combined DSS finder chart uploaded to http://master.sai.msu.ru/static/OT/J2215-1028-JRIR.jpg (10'x10' FOV).

This transient was imaged remotely with a single 180 second luminance exposure with the robotic telescope T18 of iTelescope.net at AstroCamp Observatory. Nerpio, Spain. Object measured 16.12 +/- 0.03 luminance with V as reference. Comparison stars are from UCAC4. Image: https://www.flickr.com/photos/watchingthesky/14926081550. S. Howerton
