“As anticipated in the news item from March 19, all ESO observatories have stopped science operations by now.
Paranal collected its last photons on the night of March 23\/24, with FORS2, UVES, SPHERE, MUSE and PIONIER as last instruments online.
By March 25, Paranal will have moved to a Safe State with all telescopes and instruments switched off, only essential systems for monitoring and emergencies online, and a minimal staffing on site of about 20 people (compared to 150 during operations).
La Silla had its last night of science operations on March 22\/23. All ESO telescopes (3.6m, NTT, 2.2m) and instruments have been switched off. Also hosted systems have been ramped down. A minimal staffing on site of 5 people will remain.
APEX went into ‘survival’\/mininmal mode by March 21. Telescope and instruments have been shut down and secured. At the high site, only essential systems are running with an estimated power autonomy of eight more weeks. Sequitor base camp has been secured and has supplies for the next 6-8 weeks.
Three staff will remain at the Sequitor base camp during survival mode. “<\/p>\n\n\n\n![\"\"](\"https:\/\/www.astb.se\/cassiopeiabloggen\/wp-content\/uploads\/2020\/04\/49898906_10157007841802495_2788682377931522048_n1-300x300.png\")
