Transit of Mercury

Presented by Ylva Pihlström, UNM Astronomy Professor and Associate Director of the Center for Astrophysical Research and Technologies (CART)

On Monday, November 11, 2019 a rare celestial event will occur.

Mercury, the closest planet to the Sun, will pass between the Sun and Earth, visibly crossing the surface of the Sun from our viewpoint.

Mercury will appear as a small black dot moving across the face of the Sun. This type of event will not happen again in Albuquerque until 2032.

Weather permitting, the UNM Campus Observatory will be open for the public between 8 am-11 am for this event - come enjoy it with us! In Albuquerque, as the sun is rising, we will already be seeing Mercury crossing the sun.

This is a free event and no registration is required.

The UNM Observatory is located two blocks north of Lomas and Yale NE. Both the Lomas bus #14 and the Montgomery #5 bus stop near the Observatory. Visitor parking is available at the Yale garage on the south side of Lomas for $2/hour; more information here:
