ALMA Initiates Process of Restarting the Telescope Array

With the improving pandemic situation in Chile, ALMA Observatory is pleased to take the first steps towards reopening the telescope array in the Atacama, starting with the preparation of the Observatory Operations Support Facility (OSF) at 2,900 meters above sea level for the return of staff and contractors.

The road to recovery of operations, and ultimately science observations, has been carefully planned. Regular monitoring of the pandemic is performed each week.

“We are excited about this step towards a return to operations for ALMA,” said Phil Jewell, Deputy Director for the National Radio Astronomy Observatory and North American ALMA Director. “We hope that the pandemic situation in Chile and worldwide will continue to improve and we look forward to re-establishing science operations as soon as possible.”

ALMA developed an extensive set of enhanced safety protocols related to managing the risk posed by covid-19, covering all activities as the return to operations progresses. First, preparing the OSF for the return of staff and contractors, followed by moving back into the OSF and the use of the OSF facilities, before they begin the process of restarting the Array Operations Site (AOS) at 5,000 meters above sea level.

Status updates will continue to be provided as ALMA transitions from one phase to the next in the return to full operations.

ALMA Temporarily Suspends Science Observing

Due to the COVID-19 outbreak around the world, and in order to ensure the safety of all staff, the ALMA management has decided to temporarily suspend science observing at ALMA effective Thursday, 19 March 2020. A minimal crew has been defined in order to orderly ramp down to reduced operations. The array will be stowed during this time and only when deemed safe, PI science observations will resume.

The goal is to reduce the number of people at both sites, Santiago Central Offices and the Observatory in Northern Chile, to minimize the chances of infections and thereby maximize the safety and well-being of all staff and contractors.

Radio Observatories Closing to the Public in New Mexico, Virginia, West Virginia

In response to the governors of New Mexico, Virginia, and West Virginia closing the schools in those states, the National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO) are closing their facilities in all three states. The closures affect the staffs and the visitor centers at the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) in New Mexico, the Robert C. Byrd Green Bank Telescope (GBT) in Green Bank, WV, and NRAO Headquarters in Charlottesville, VA.

Under the closures, skeleton staffs will maintain scientific observing with the VLA, the Very Long Baseline Array (VLBA), and the GBT, and the remainder of the staffs will work from home as possible. Staff members working from home will be accessible via email and will endeavor to continue providing services. The visitor centers at both observatories will be closed to the public.

“Our priority is to protect the health of our staff and also to do our part in helping our states and communities combat the nationwide outbreak of Cornonavirus-19 Disease (COVID-19),” said Tony Beasley, Vice President for Radio Astronomy of Associated Universities, Inc., the organization that operates both NRAO and GBO for the NSF.

To date, no employees of either observatory have been diagnosed with COVID-19.

“As long as we can, we will continue to provide the service to the scientific community that is our mission. These measures seek to maximize the social distancing that will help reduce the spread of this disease,” Beasley said.

Observatory officials will continuously monitor the situation and the recommendations of the Centers for Disease Control and Prevention as well as of state agencies, and will take additional measures if necessary.

“This is a difficult time for our observatories and our nation, but I am confident that our team can support these public health initiatives and help keep our colleagues and our neighbors as safe as possible,” Beasley said.

The National Radio Astronomy Observatory and the Green Bank Observatory are facilities of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.
