NASA-funded Arecibo Planetary Radar system was tested for the first time since hurricane Maria with a successful detection of near-Earth asteroid 2007 AG. This object at its closest approach to Earth will be some 0.059 AU and is estimated to be 300 meters in diameter

Columbia, MD and Puerto Rico — December 22, 2017. After several months of downtime since Hurricane Maria struck the island of Puerto Rico, the Arecibo Observatory Planetary Radar has returned to normal operation, providing the highest-resolution images to date of near-Earth asteroid 3200 Phaethon during its December 2017 close approach to Earth. The radar images, which are subtle at the available resolution, reveal the asteroid is spheroidal (roughly ball-shaped) and has a large concavity, or depression, at least several hundred meters in extent near its equator, and a conspicuous dark, circular feature near one of the poles. Arecibo’s radar images of Phaethon have resolutions as fine as about 250 feet (75 meters) per pixel. Read More
