Nova M81 PNV J09554017+6902478, Orimattila, Artjärvi, Viestikallio

A possible nova has been observed in the M81 galaxy, according to the announcement received yesterday, October 2, 2021, around mag20 various very dim. At the end of a gusty night, I exposed the light from the M81 through a 16 * 1min Baader Clear filter to see if it could be seen. The boundary magnitude in a single 60s exposed image is about 19.0, so moving the limits of the vehicle’s performance is moving. In addition, the M81 effectively obscures Nova, which may be quite close to its core, with its light, so a negative observation of this is recorded even if something ashy at the assumed point may be visible.
