I have carried out magnitude measurements of Mars.
For 8 December I found magnitudes of
V-filter +1.67 LCM=298degW R-filter +0.41 LCM=293degW I-filter -0.07 LCM=289degWMars was slightly dimmer than the predicted magnitude, but this is probably due to Syrtis Mj which was near the CM.
In the meantime I hope that you and your family have a blessed Christmas and a Happy New Year.
