Thursday, March 6 - Mt. Hopkins Rd. Closure

Mt. Hopkins Road will be closed for most of the day on Thursday, March 6, starting at 9:00am. It will be open from noon - 12:30pm, then closed again until 4:00pm. Contractors will be digging holes to locate power lines near 5.5 km. Utility power will be disconnected while this work is being performed with power provided by generator during this time.

Mt. Hopkins Road - Currently open through Monday, March 17

Road repair work is continuing on the Mt. Hopkins Road intermittently in March around km 5.5 and km 12.  When scheduled, work will be conducted on weekdays, with the road usually scheduled to be open before 8:30am, from noon-12:30pm, and after 4:00pm, although it might vary day to day. The road will be open on weekends. Observers will receive emails giving the current status of the road before and during their observing runs.

Meteor in Tucson

On Tuesday, December 10, at 7:11pm, a sonic boom hit Tucson as a large meteor passed overhead. MMT's all sky camera captured its bright flash in a single image. The frame shows the moon (center) and the meteor (upper).

Facility Improvements at the MMT

Work began in October on the installation of a new comprehensive fire alarm system at all of the facilities on Mount Hopkins.  Work remaining at the MMT is expected to be completed by mid-December. Work continues at the other mountain facilities and at the Administrative Complex at the basecamp area. 

Construction improvements at the Common Building began in November and are expected to be finished in December. The work includes sealing leaks, repairing interior drywall in the basement, and touching up exterior paint.

Evidence for Densest Nearby Galaxy

The MMT was one of the ground-based telescopes, along with the Hubble Space Telescope and the Chandra X-ray Observatory, used in studying a nearby and very dense galaxy, M60-UCD1. Read NASA's press release and the paper

Dual Supermassive Black Hole Candidates

Using publicly available data from the AGN and Galaxy Evolution Survey (AGES), conducted at the MMTO with the hectospec instrument, researchers have discovered seven new candidates for dual supermassive black hole systems in the centers of galaxies. Based on the new findings, they suggest that the number of galaxies containing dual supermassive black holes decreases over time, likely because more galaxies merged together in the past. AGES is a joint Arizona/CfA collaboration.
