A possible nova in Aquila was discovered by Stanislav Korotkiy (Ka-Dar Obs./Astrovert) and Kirill Sokolovsky (MSU/SAI MSU/ASC Lebedev) on three images, obtained on 2020 Jun 13.9463UT with a wide-field survey camera (F=135mm f/2.0 telephoto lens and ST8300M unfiltered CCD, 20sec exposure time) at Ka-Dar Observatory's TAU Station/Astrovert, Nizhny Arkhyz, Russia (MPC COD C32). The object is clearly visible at magnitude 12.2 +/-0.1. The limiting magnitude of the images is ~13.5 (the scale is calibrated using V magnitudes of Tycho-2 stars in the field). Initial astrometry using nearby UCAC2 stars (RA, Dec, J2000): 19:06:20.62 -03:27:55.4 +/-1". The object is not visible on our previous images obtained on Jun 08.8678UT (limiting mag. 13.0). The USNO-B1.0 catalog lists USNO-B1.0 0865-0445001 (magnitudes B1=17.76, R1=15.11, B2=17.20, R2=15.56, I=14.04mag) just 1.4" away from the above position. The object could not be identified as a previously known one using MPChecker, AAVSO VSX and SIMBAD.

After a closer inspection of the region with Aladin Sky Atlas we realized this transient is a UV Ceti-type flare of a red dwarf 2MASS J19062064-0327540 = Gaia DR2 4260750876430575744 (19:06:20.65 -03:27:54.5 J2000 position at the Gaia reference epoch 2015.5, distance 104 pc). We apologize for any inconvenience caused by reporting this flaring red dwarf to the TOCP rather than to AAVSO VSX. ---- Kirill Sokolovsky and Stanislav Korotkiy
