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).

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. N
