We are pleased to announce the public release of the "Flash Detection Software", which was developed by the National Observatory of Athens for ESA. We invite both amateur or professional astronomers performing planetary observations with video cameras or fast-frame CMOS/CCDs to test it.
The Institute of Astronomy Astrophysics Space Applications & Remote Sensing of the National Observatory of Athens operates Helmos observatory, which was selected as the first Optical Ground Station under the ScyLight framework. Project HOTSPOT (https://artes.esa.int/projects/hotspot) aims to identify all possible activities that can be carried out at Helmos observatory in Greece concerning optical, quantum, and deep space communications.

A poster presentation on the capabilities of the Kryoneri telescope regarding its instrumentation was given at the Europlanet Telescope Network Science Workshop, which took place (virtually) between February 9-11, 2022.
Constraints on the structure and seasonal variations of Triton’s atmosphere from the 5 October 2017 stellar occultation and previous observations
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of which yielded a central flash detection. We aimed at constraining Triton's atmospheric structure and the seasonal variations of its atmospheric pressure since the Voyager 2 epoch (1989). We also derived the shape of the lower atmosphere from central flash analysis.
The Institute of Astronomy, Astrophysics, Space Applications and Remote Sensing (IAASARS) of the National Observatory of Athens (NOA) successfully observed the flyby of asteroid 7482 (1994 PC1) with the 1.2m Kryoneri telescope.
We are happy to announce the extension of the NELIOTA project for two years. Starting in August 2021, the project is funded by ESA through the project Consolidating Activities Regarding Moon, Earth and NEOs (CARMEN, contract No. 4000134667/21/D/MRP), coordinated by 6ROADS, until July 2023.
The Institute of Astronomy, Astrophysics, Space Applications and Remote Sensing of the National Observatory of Athens organizes for the summer months, astronomy evenings at the Kryoneri Observatory in Corinth.
We present the results of our ground-based astrometric observation campaign of BepiColombo during its Earth fly-by on 2020 April 10. The observational circumstances induced by the fly-by geometry made this event an excellent proxy for a close fly-by or an imminent impact of a natural body with a diameter of a few meters, with the added benefit of having a ground-truth orbit (from radio tracking) to compare with our purely ...
On the evening of April 15th, IAASARS hosted a virtual tour of Kryoneri Observatory, which included live viewing of the Moon through the 1.2 meter telescope, a presentation of the facilities and the lunar monitoring research program NELIOTA.
