Excerpts from CBET 4811:
"Robert H. McNaught, Coonabarabran, NSW, Australia, has found an apparent 5th-magnitude nova on CCD images obtained on July 15.590 UT with a Canon 6D camera and an 8-mm-f.l. f/2.8 lens"
"... he obtained visual mag 5.3 with 2.3x40 opera glasses (using AAVSO A chart for MGAB-V207)."

The eruption apparently began already on 2020 July 4.
Spectroscopy, multiband photometry, and precise astrometry are urgently required.
Clear skies,

Hi All,
I am part of a group that distributes information about potential multi-instrument simultaneous observing opportunities. As part of this group, I saw an alert about NuSTAR observations of this source. Since I am not directly involved with this science, I'm not sure how useful simultaneous X-ray + optical observations are. But in case they are I wanted to post the planned observation times.
2020:199:23:35:16
2020:201:10:45:00
This translates to July 17, 2020 (tonight) from 23:35:16 UTC to July 19, 2020 10:45:00.
I am hopeful the people more directly involved with this outburst can comment on potential research applications and collaboration between professional astronomers and AAVSO members/observers.
Sincerely,
Greg Sivakoff
