“PNV J19450648+1822422 was originally discovered by the NMW-TexasTech
survey. Its position coincides with a known eclipsing binary candidate
in Gaia, with an orbital period of 9.9011 d. Thus, time-resolved
observations may reveal eclipses during its decline as the photosphere
recedes.”VSX details of precursor (g~20): https://vsx.aavso.org/index.php?view=detail.top&oid=10762522
There is now a chart and sequence available from AAVSO VSP, though I had some difficulty downloading just now, so appending here (5 deg field).
The brightest star, left of centre) is delta Sagittae.
