How bright is comet Leonard? The photometry of the green channel (nov. 30 UT 3.40) of a four minute exposure with the tele F-135/2.8 gives 6m7 (Gaia Broadband), and 6m8 with UCAC4 vis. ! The aperture is 720". This would be much brighter than expected if confirmed, when the moon has gone. Michael Jäger
