It was just a bit of wind

An unusual footnote to the official telescope scheduling email :

(a) As you are probably aware, Puerto Rico was severely affected by Category 4/5 Hurricane Maria which decimated the island on September 20th, 2017. Even today, some 45% of our population have no access to electric power, many having no municipal water supply either. The eye of the storm passed over Arecibo Observatory, probably the most serious damage being the destruction of the 430-MHz Carriage-House line feed, which snapped about one-third of the way down its length. Its falling debris caused some damage to the dish surface. Nevertheless, our amazing staff had the telescope back "on the air" remarkably quickly, and 327-MHz pulsar drift-scan searches were soon being made again, followed up by L-band spectral-line and pulsar programs, atmospheric 430-MHz (Gregorian) and S-band planetary radar studies, and VLBI with RadioAstron at L- and C-band. A new pointing model has been determined and installed, and pointing is believed to be close to its pre-hurricane quality. While single-dish observations at and above 5 GHz are presently not being scheduled, the observatory staff are investigating the sensitivity at these higher frequencies, and it is expected that such observations will be recommenced before too long. Accepted proposals requesting observing modes currently affected by the ravages of Hurricane Maria will be scheduled as soon as is considered practical.
