Articles on the National Geographic and Space.com websites report that scientists and Amateur Radio operators have confirmed that Puerto Rico’s Arecibo Observatory came through Hurricane Maria largely intact but “with some significant damage.” Universities Space Research Association (USRA), which helps to operate the Observatory, said it learned via “short wave radio contact” that staff and family members sheltering at Arecibo are safe.
“The major structures, including the 300-meter telescope, are intact, though suffered some damage when the atmospheric radar line feed broke off, and falling debris from it punctured the dish in several places,” USRA reported on its website. “Also, a separate 12-meter dish used as a phase reference for Very Long Baseline Interferometry was lost.”
Observatory officials are still assessing the damage, but Jim Breakall, WA3FET, of Penn State, told ARRL that the 96-foot line feed antenna at 430 MHz is “historically the key piece to the observatory.” It’s also the antenna that he and others have used for Amateur Radio moonbounce activities from Arecibo. The Observatory is home to KP4AO.
“To hear that this 10,000-pound key piece to the Observatory fell and hit the 1,000-meter dish is just a huge shock,” Breakall said Saturday. “This antenna was connected to the 2.5 million W 430-MHz radar transmitter that was a key to ionospheric experiments. It is a great loss for sure.”
Angel Vazquez, WP3R — the Observatory’s telescope operations manager — was among the only radio amateurs able to pass along any information; among those he contacted was Princeton University professor and Nobel Laureate Joe Taylor, K1JT. Vazquez is using a generator that, Breakall told ARRL, was not working very well. “Many others have heard about all of this and have come to help relay messages to loved ones and friends to let people know they are okay,” Breakall added.
Breakall said he’s less concerned…
