St. George Astronomy Group

The St. George Astronomy Group is an informal  association of amateur astronomers in St. George, Toquerville  and other nearby communities in southwest Utah.

The group was formed to (a) exchange ideas and foster fellowship among people with an interest in astronomy, (b) to host public star parties, and (c) to promote proper lighting and dark skies over southwest Utah.

There are no officers, dues, or formal meetings. Membership is open to anyone who wishes to actively participate in hosting star parties and working for dark skies over St. George.

People who wish to know about the group's public activities can join our mailing list.


Free Public Viewing of Rare

“Transit of Mercury”

Monday, May 9th


On the morning of Monday, May 9th, the tiny planet Mercury moves directly in front of the sun and for a few hours moves across the sun’s face in a “transit of Mercury.” These events are rare – the last transit of Mercury was in 2006 and the next won’t be until November, 2019.


During the transit an observer can see Mercury silhouetted in front of the sun’s disk. Mercury is not much larger than our moon, and at a distance two-thirds the sun’s it looks like a tiny black dot smaller than most sunspots. Mercury’s motion is too slow to watch -- slower than the movement of the hour hand of a clock -- but in several hours it moves from one side of the sun to the other.


You can see the transit only with a properly filtered solar telescope. The St. George Astronomy Group will provide solar telescopes for free public viewing in downtown St. George at Town Square (50 South Main Street), adjacent to the public library, from 9:00 a.m. until 12:40 p.m. Family friendly; everyone is invited. Clouds cancel.


At least part of the transit is visible simultaneously with the proper equipment to people everywhere except easternmost Asia and Austra­lia; adjust for time zones if necessary.
