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.
NELIOTA cameras used to observe Triton's occultation
The NELIOTA fast-frame cameras were successfully used to observe the occultation of Neptune’s moon Triton on October 5th, as part of a campaign led by Dr. Bruno Sicardy and the "Lucky Star" team, of the Paris Observatory, France. Light curves of the occultation were obtained simultaneously in the I and R-bands. Preliminary photometry shows a ~1 mag dip. The ground trace of the occultation is shown on the left (Credit: Google, INEGI, ORION-ME).
New multi-frame flash
On September 16, 2017, NELIOTA recorded a bright flash at the edge of the monitored area, which appeared on several frames. It was recorded on 7 I-band and 3 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.
