Dear Friends,

ASAS-SN light curve:
https://asas-sn.osu.edu/light_curves/c04780d4-c91f-4003-b4d0-a70aa166936c

The light curve is probable contaminated with a 15.7G mag (16.2V in 
APASS) star located only 8" from Gaia19edn. (That star is Gaia DR2 
4060063199439915264 or USNO A2.0 0600-27892004.)

Gaia19edn 20190912.1428 <15.9g	ASN
Gaia19edn 20190912.1441 <15.88g	ASN
Gaia19edn 20190914.855	<14.85g ASN
Gaia19edn 20190914.8787 <15.44g ASN
Gaia19edn 20190914.8811 <15.62g ASN
Gaia19edn 20190915.0962 <16.17g ASN

and even the positive detections on 20190915.7895 (16.075g) and on 
20190915.8512 (15.51g) have large errors (0.191 and 0.162 respectively).

Thus I assume this nova candidate might be highly reddened.

Clear skies,
