| 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

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.
