Event: Nova Scorpii 2015 = PNV J17032620-3504140

Discovered by: Tadashi Kojima, Gunma-ken, Japan

Discovery magnitude: unfiltered DSLR magnitude 8.1, using a 150-mm f/2.8 lens and digital camera

Discovery date: 2015 February 11.837 UT

Coordinates: RA: 17 03 26.18 , Decl: -35 04 17.6

Spectra: Echelle spectra by Frederick Walter (Stony Brook University) taken on 2015 February 13.40 and reported in Astronomer's Telegram #7060 indicate the presence of strong H-alpha with FWHM of 2000 km/s, along with several other emission features. See ATel #7060 for details.

Observing recommendations: Observations of all types (visual, CCD, DSLR,
spectroscopy) are strongly encouraged in following the evolution of this nova.
