In Europe, one had to go to the southwest of the Iberian Peninsula to observe the occultation before sunrise.
I prepare for the event as if it were a solar eclipse.
I take a flight to Lisbon with the C8 in my backpack and I decide to settle near Alcacer do Sal to take advantage of a grazing occultation: the lunar disc will "eat" the red planet while leaving its north pole visible.
Thus, Mars will reveal the rounded shape of the limb on the dark side of the Moon, as visible in the composite image.
The processing of the 400 video sequences of 4s each and their registration on Mars required several tens of hours of work!
