TRANSIENT IN SCORPIUS = TCP J17154683-3128303 Koichi Nishiyama (Kurume, Japan) and Fujio Kabashima (Miyaki, Japan) report their discovery of a magnitude 10.1 transient in Scorpius at: RA 17h 15m46.83s DEC -31 28’ 30.3” (2000) on 2014 Mar. 26.848UT on unfiltered CCD. They confirmed the discovery on unfiltered CCD frames taken 2014 Mar 26.869UT. Survey frames from 2014 Mar 22.819 UT (limiting mag.= 12.5) and 23.836 UT (limiting mag.= 12.9) show no object, nor does DSS or USNO-B1.0. The nearest star in the DENIS Database has position end figures 46.861s, 30.48", distance 0.44", magnitude I=14.222. Rob Kaufman (Bright, Vic, Australia) reports a reddened object at mag ~V=11.6 (unfiltered DSLR image) on images of 2014 Mar. 27.653 UT. Seiichiro Kiyota (Kamagaya, Japan) reports Rc=10.36, Ic=9.74 using TYC 7362-449-1 as a comparison on his images from 2014 Mar. 27.7091 UT.

The Astronomer’s Telegram 6015 reports that Swift observations taken only hours after the discovery (March 27 03:39-03:51 and 04:42-04:51 UT) reveal a new, bright, X-ray source. The source is also seen in UVOT, with uvw1 magnitudes of 12.58 +/- 0.02 and 12.61 +/- 0.02, for the 2 snapshots, respectively. The positions they derive are consistent with the optical discovery position. The mean X-ray spectrum is consistent with an (expanding) shell in a nova. The position was covered during an XMM-Newton slew on UT 2011 March 4, but no source was seen with a 0.2-12 keV 2-sigma upper limit of 0.54 c/s. Follow-up Swift ToO observations for the next days have been approved. AAVSO advise TCP J17154683-3128303 has been added to VSX. Finder charts with a comparison star sequence for TCP J17154683-3128303 may be created using VSP. Please report observations to TA/BAA/AAVSO as TCP J17154683-3128303.
