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.

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.
