Lightening strikes illuminate the ATCA site in Narrabri
Observers at CSIRO's Australia Telescope Compact Array (ATCA) always watch out for severe weather events, especially thunderstorms and lightning. For safety reasons the dishes are stowed when winds reach speeds above 40 km/h. Lightening can cause power outages, so we switch on backup generators to avoid interrupting telescope operations. Our radio telescopes observe 24 hours every day of the year, apart from short periods of maintainance. - The photo above was taken by Angel Lopez-Sanchez (UMQ/AAO), @El_Lobo_Rayado. -- The ATCA consists of six 22-m dishes operating together as a 6-km diameter radio interferometer. It is located just outside the town of Narrabri in New South Wales (NSW), Australia.
