Event:  Nova in Orion: N Ori 2019 = PNV J06095740+1212255

Discovered by: Shigehisa Fujikawa (Kan'onji, Kagawa, Japan)

Discovery magnitude: 9.4 unfiltered CCD (using a Minolta F 3.5 f 120mm lens, limiting mag 13.5)

Discovery date: 2019 August 07.7984 UT

Coordinates (2000.0): R.A. 06 09 57.45   Decl. +12 12 25.2  (from VSX)

Spectra: Spectroscopy obtained by E. Aydi et al. (ATel #13027) on 2019 August 14.44 UT using the Goodman spectrograph on the SOAR telescope indicates that N Ori 2019 is a very fast expanding classical He/N nova, possibly in the post-maximum phase.

Observing recommendations: Observations of all types (visual, CCD, DSLR, PEP, spectroscopy) and multiple bands as instrumentation permits are strongly encouraged as the nova evolves.
