Mercury has an odd orbit and day night cycle.

3 days per “Mercurian” year with the length of day varying with the planet’s distance from the sun. From what I’m reading the sun would be nearly dead still in the sky at perigee.

From what I’m reading the sun would be nearly dead still in the sky at perigee.

At both 90° Longitudes you get a triple sunrise/ sunset

In the morning in the east

The sun will rise then turn around and set (still in the east) then re-rise again in the east

A mercury day later

The sun will set in the west but then it will re-rise (in the west) and then set again.
