Astronomical Institute in ESA-funded projects

The Institute was recently involved in two new ESA-funded research and development projects. Cheia Antenna Retrofit Phase II is a project led by RARTEL Telespazio, a Leonardo and Thales company, aiming to include the 32 meters antennas presently available at the Cheia Satellite Ground Station, in the context of European SSA programme. The Institute will assist RARTEL in all the project phases (design, software development, integration and testing) for all the aspects related to the tracking services which shall be supplied through the newly developed radar infrastructure.

SYNOPTES project, led by Romanian InSpace Engineeering startup and having both Cluj and Bucharest observatories as partners, is developing a GNSS-based real-time clock (RTC) system for the temporal synchronization of SST ground based observations. Berthelot and Feleacu astronomical stations are the testing beds and on-sky validation infrastructures of the technical solution. Contact: nedelcu (at)

During the presentation of Daniel Berteşteanu, the public received special glasses for spectroscopy aplications.

Bucharest Science Festival 2019

Bucharest Science Festival opened the gates of the Astronomical Institute of the Romanian Academy for the general public, on the 27th of September 2019. The number of visitors exceeded any estimations being around 500 adults and children.

The Planetarium Hall was permanently full of people eager to learn who participated to several presentations with PowerPoint, video or specialized software support. The academic staff and astronomy teachers were: dr. Diana Beşliu-Ionescu (AIRA), Daniel Berteşteanu (Bucharest Astroclub), Florin Zăinescu (University of Bucharest).

A special moment of the evening was the live connection with France, as dr. Mirel Bîrlan (AIRA) interacted with the public through Skype directly from Paris Astronomical Observatory.

The activities included guided tours in the museum halls of the Institute - the Meridian Hall and the Equatorial Dome. There, some of the most important and spectacular astronomical instruments of Romania are preserved for future generations and they are used today for educational purposes.The tour guides - Sorin Marin (AIRA), Octavian Blagoi (AIRA) and Marian Naiman (Bucharest Astroclub) received many questions during the whole event, especially coming from the younger friends of astronomy and they answered to all of them.

The members of Bucharest Astroclub took part in organizing the BSF 2019 event. They displayed with great openness their instruments - several telescopes and their accessories and kindly instructed the public on how to watch the planets and the stars through them.

First Interstellar Comet

Using Berthelot Observatory in remote mode we imaged the first interstellar comet - C/2019 Q4 (Borisov) . Based on the current arc, the comet is on a hyperbolic orbit with an eccentricity of almost 3. The comet will reach perihelion on December 7, 2019. Berthelot Observatory will continue to monitor this objects in the following weeks. Contact: sonka (at)
