Mercury Viewing at ASU

Angelo State University Planetarium Director Dr. Mark Sonntag is inviting the public to join him for a special viewing of a Mercury transit on Wednesday, Nov. 8, at the Vincent Nursing-Physical Science Building on the ASU campus.

Transits of Mercury occur only 13 times a century when Mercury passes between the Earth and the Sun in the plane of the Earth's orbit. However, each transit is only visible from about half of the Earth's surface. The last transit of Mercury visible from San Angelo was on Nov. 15, 1999, and the next one will not be until May 9, 2016.

The Nov. 8 transit will begin at about 1:12 p.m. and will be visible until sunset. Weather-permitting, Sonntag will have a telescope set up outside the Vincent Building, 2333 Vanderventer, from 1-3 p.m. to observe the event and the public is invited to participate.

For more information, call Sonntag at 942-2136, Ext. 224.
