Multi-frame flash detected on September 5, 2018
On September 5, 2018, NELIOTA recorded a bright flash, which was caught before maximum and appeared on several frames. It was recorded on 12 I-band and 4 R-band images. Τhe animated gif shows the flash as recorded in the I-band. More details on this lunar impact flash are available here.
NELIOTA: second scientific publication
The second scientific publication of the NELIOTA project was accepted in Astronomy & Astrophysics on August 31, 2018 and is titled “NELIOTA: The wide-field, high-cadence lunar monitoring system at the prime focus of the Kryoneri telescope". The paper presents the NELIOTA system deployed on the refurbished 1.2 m Kryoneri telescope, the NELIOTA software, instrument performance and results of the first year of NELIOTA observations. NELIOTA is the first astronomical system to use sCMOS detectors at a fast-frame rate. Our observations so far suggest a detection rate of 1.96 × 10−7 events km−2 h−1.
NELIOTA: first scientific publication
The first scientific publication based on the NELIOTA project was accepted in Astronomy & Astrophysics on January 2, 2018 and is titled “NELIOTA: First temperature measurement of lunar impact flashes”. The paper reports the first scientific results from NELIOTA, in particular a direct analytical calculation of temperatures of 10 lunar impact flashes. The resulting values for the flash temperatures are in the range ~1,600-3,100 K, in agreement with theoretical values. The impactor masses are computed to have values in the range between ~100 g and ~50 kg.
