ASASSN-19nl: likely dwarf nova outburst (14.4 mag, in Cygnus)

ASASSN-19nl (UG:)
https://www.aavso.org/vsx/index.php?view=detail.top&oid=689715

Reddish at quiescence (but identification somewhat uncertain). Previous outburst on 2016 June 20. Complete ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) data and light curve: https://asas-sn.osu.edu/light_curves/5178e905-1fc1-4c00-9880-3191c57107b3

Precise astrometry (or at least a snapshot), spectroscopy, and multiband photometry are urgently required.

Clear skies,
Patrick

No AAVSO observations yet

Fading: https://asas-sn.osu.edu/light_curves/afe2348d-4635-4c10-abde-d023b12c7a9d

Still no observations reported to the AAVSO. At least a snaphot is urgently required.

Clear skies,

I pointed at this one last night and did not pick it up. It looks like this one has really faded. I noticed someone provided observations a night or two ago but I'm not sure that is on the correct star based on my images and the magnitude.
