[vsnet-alert 19889] Re: [cvnet-outburst] PNV J17381927-3725077: new transient (12.4 mag) in Scorpius

[Josch Hambsch]

This star got even brighter. I measured it last night from Chile at mag 11.4 with clear filter.

I took a time series. Maybe I should use a V filter for tonight?
It is not yet in the AAVSO database (at least not with the name mentioned below).

Regards,

Josch

PNV J17381927-3725077

Discoverer: Hideo Nishimura (Shizuoka-ken, Japan)

R.A. 17h38m19.27s  Decl. -37°25'07.7"  (J2000.0)
2016 June 10.629 UT, 12.4 mag (CCD, unfiltered)

"2016 06 10.629 UT
Discovered by H. Nishimura, Shizuoka-ken, Japan using 200-mm f/3.2 lens + a Canon digital camera EOS 5D, who writes nothing is visible at this location on his recent frames taken on 2016 May 14.712, May 18.602 and June 5.532 (Limiting mag = about
13.0) UT using same patrol camera."

Two USNO-B1.0 stars (both about 17 mag) are within 1" of the transient's position.

Spectroscopy, precise astrometry, and time- resloved photometry are required.
 
Clear skies,
Patrick
