I correct the report I made yesterday as follows : 2015 09 27.447 18 03 33.6 -28 16 10 10.5U The image of this object is posted at : https://sites.google.com/site/akitakao001/




2015 09 28.0818

Photometry results were B=9.77, V=9.18, Rc=8.83 and Ic=8.48 with 0.43-m f/4.5 CDK astrograph + FLI-PL6303E at Mayhill, USA, remotely. Seiichiro Kiyota (Kamagaya, Japan)




2015 09 28.4083

Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Nova in Sgr (TOCP Designation: PNV J18033275-2816054), I performed some follow-up of this object through a 0.43-m f/6.8 astrograph + CCD from MPC Code Q62 (iTelescope Observatory, Siding Spring). On images taken on September 28.4, 2015 I can confirm the presence of an optical counterpart with R-filtered CCD magnitude 9.5 at coordinates: R.A. = 18 03 32.77, Decl.= -28 16 05.3 (equinox 2000.0; UCAC-4 catalogue reference stars).

Photomety: B= 9.6, V= 9.2, R= 8.9, using 0.30-m f/9.9 Cassegrain + CCD + f/7.0 focal reducer at Osaki Lifelong Learning Center, Japan. Observer T. Yusa, Y. Suzuki, C. Shirotori, N. Endo and A. Endo, Osaki, Japan. An image is put on URL http://space.geocities.jp/yusastar77/supernova/PNinSgr_151003.htm
