Matthieu Conjat reports the discovery of a possible nova (mag 19.8) on 150s images taken with the Schaumasse telescope at the Observatory of Nice (400mm f/5 Cassegrain telescope). Total integration time is 2000s. Images taken on 15 march 2020 19h17 TU show a transient object at approximate position 09 55 27.1 +69 37 46 (J2000). Object is not visible on previous images taken on 07 March with the same instrument and integration time. Camera used is a QSI583ws with Clear filter.

Matthieu Conjat reports the discovery of a possible nova (mag 19.5) on 150s images taken with the Schaumasse telescope at the Observatory of Nice (400mm f/5 Cassegrain telescope). Images taken on 15 march 2020 19h17 TU show a transient object at approximate position 09 55 33.2 +69 40 47 (J2000). Object is not visible on previous images taken on 07 March with the same instrument and integration time. Camera used is a QSI583ws with Clear filter.

Mi Zhang and Xing Gao, report the discovery of a possible nova (mag approximately 19.9) on several 300-s survey images (limiting mag about 21.0) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Mar. 16.74830 UT using a r'(Sloan) filtered CCD (+ 0.6-m f/8 Ritchey-Chretien telescope). The transient approximately located at R.A.=09h55m32.63s +69d40'47".2 (equinox 2000.0). Which is about 103.2" west and 0.3" north of the center of the M82. Nothing is visible at this position on archival images taken on Mar. 14.61644 UT(limiting mag 20.5).
