Asteroid Day 2017 at Kryoneri Observatory
On June 30th, the National Observatory of Athens and the Youth Cultural Society of Kryoneri hosted an open night for Asteroid Day 2017 at Kryoneri Observatory. Over 400 people attended the event, which included a tour of the 1.2m Kryoneri telescope, viewing of the Moon, planets and other celestial objects through telescopes set up by members of the Hellenic Astronomical Union, and talks by Dr. Bonanos on the danger posed by near-earth asteroids and by Dr. Dapergolas on the Kryoneri telescope.
ESA press release: New NELIOTA project detects flashes from lunar impacts
Using a system developed under an ESA contract, the Greek NELIOTA project has begun to detect flashes of light caused by small pieces of rock striking the Moon’s surface. NELIOTA is the first system that can determine the temperature of these impact flashes.
"Its large telescope aperture enables NELIOTA to detect fainter flashes than other lunar monitoring surveys and provides precise colour information not currently available from other projects," says Alceste Bonanos, the Principal Investigator for NELIOTA.

First lunar flashes detected by NELIOTA
We are proud to announce that NELIOTA has so far detected 5 lunar flashes. Parameters of all flashes are available via the Data Access page of the NELIOTA website. The brightest flash detected so far peaked at 6.7 mag in R and 6.0 mag in I and had a duration of 0.13 seconds, while the faintest flash peaked at 10.0 mag in R and 8.7 mag in I and lasted 0.03 seconds.
