Description
We report the discovery of two novae in M81 on a co-added 1600-s
narrow-band H-alpha CCD image taken with the 2.5-m Isaac Newton
Telescope (INT) + WFC at La Palma under ~0.8" seeing on May 22.901 UT.
The new objects are well visible on the co-added image (see the finding
chart linked below) as well as on individual 400-s frames, but are not
present on numerous narrow-band H-alpha archival images from the INT
down to limiting magnitude as faint as H-alpha = 22.3.
