Due to continued roadwork, restrictions will be in place on Dec. 8-9 with road openings at 8:00-8:30am, noon-12:30, and after 4:00pm. On Dec. 10 & 11, the road will close at 8:30am and reopen at 4:00pm each day while work is done around km 9. A walk-through will be in place with vehicles available on either side. On Dec. 12, there will again be restrictions with the road open at 8:00-8:30am, noon-12:30, and after 4:00pm. Call 520-879-4422 for recorded updates.
Culvert replacement will be conducted around km 7 on December 3 & 4, resulting in an overnight closure of the road at that area. The road will close at 8:30am on Dec. 3 and reopen after 4:00pm on Dec. 4. A walk-through will be in place with vehicles available on either side for use by observers and staff. Current plans are for restrictions to be in place on Dec. 5, with road openings at 8-8:30am, noon-12:30, and after 4:00pm. Check back here for updates.
Cochise County, Arizona, has recently updated its lighting codes with the latest lighting technology in mind. The result is more protection for observatories and astronomy, while allowing enough light for the needs of businesses. Read about the county leading the way in the state!
Researchers at ASU recently announced the discovery of a wide brown dwarf companion to the nearby star zeta Delphini using data taken at the MMT with the ARIES instrument. The star and its brown dwarf, which are about 67 parsecs away, were observed as part of a larger survey of nearby stars called VAST (Volume-limited A-Star survey). The brown dwarf is located quite far away from its host star - about 900 times the distance between the Earth and the Sun - and is among the most widely separated companions known to date.

Implementation of well-planned lighting codes can help Arizona's astronomy industry, as well as keep residents safe. Read more about the effects of light pollution.
Dr. Margaret J. Geller, Harvard/CfA astrophysicist, was recently awarded this year's Karl Schwarzschild Medal of the German Astronomical Society.
