Transit of Deimos from Mars

During a transit, Deimos can be seen from Mars as a small dark spot rapidly moving across the Sun's face.

A transit of Deimos from Mars lasts a maximum of about two minutes, due to its relatively rapid orbital period of about 30.3 hours.

At any given geographical location on the surface of Mars, there are two intervals in a Martian year when the shadows of Phobos or Deimos are passing through its latitude.

The shadow always falls on the "winter hemisphere", except when it crosses the equator during the March and September equinoxes.

A transit lightcurve of Deimos was obtained[3] in 2020 using the solar array currents measured by the InSight lander.
