Come out and view our star!

The James Webb Space Telescope, which launched on Christmas Day 2021, achieved its final operational configuration on January 8, 2022, when the observatory was still about two weeks travel time from its halo station orbit at the L2 Lagrange point about a million miles from Earth. Webb began its multi-year science mission after about six months of calibration and alignment in July of 2022.  Webb is designed to see back in time to the birth of the first stars and galaxies, study the formation and evolution of galaxies, understand the formation of stars and planetary systems, and study planetary systems and the origins of life.

Virtual Tour

The Patterson Observatory named after  Mr. David Patterson

Patterson and his wife, June, were founding members of the Huachuca Astronomy Club and volunteers at the Flandrau Planetarium in Tucson, Arizona.

Patterson was a major contributor to the creation of the observatory, including the purchase of the telescopes, and constructing the building.

 

His legacy continues to support the observatory and the University South Foundation.

Colombo Avenue, Sierra Vista AZ, I agree to hold harmless the Patterson Observatory, The University South Foundation, Inc., the University of Arizona, South and the Huachuca Astronomy Club of Southeastern Arizona (also known as HAC or the Huachuca Astronomy Club), including their members, officers and sponsors from any claims, liabilities, losses, demands, causes of action, suits and expenses (including attorney fees and costs), which may directly or indirectly be connected to my attendance at the hosted event, my participation at the event, or my presence on the premises of the Patterson Observatory and/or the University of Arizona, Sierra Vista campus. I understand that these events are, by their nature, conducted at night and in environments with low levels of lighting, or no lighting, so as not to interfere with the ability of participants to view objects through various telescopes.  Additionally, I understand that I may be required to climb ladders, or stairs, in very low light conditions, or in the absence of light, to properly utilize the telescopes”.
