About the PROBA2 Science Center

PROBA2

The PROBA2 Science Center, located at the Royal Observatory of Belgium in Brussels, oversees scientific operations and data processing for ESA's PROBA2 spacecraft. The P2SC is the primary archive and distribution center for data from SWAP and LYRA, as well as the primary maintainer of calibration tools, data analysis software, and additional instrument data. The P2SC is also home to the science operations center, where instrument observing plans are devised and, with the help of ESA's Spacecraft Operations Center in Redu, Belgium, loaded onto the spacecraft. Finally, the P2SC serves as the main site for coordination of the PROBA2 Science Working Team, coordinating special scientific campaigns, supporting science data users and guest investigators, and organizing PROBA2 outreach efforts.

PROBA2 is a small ESA satellite with a scientific mission to explore the active Sun and its effect on the near-earth environment and a broader mission to provide a test platform for new instrument and platform technology. The mission overview page provides additional information about PROBA2 and its on board instrumentation and advanced platform technology.

Release of a new LYRA product: O+N₂ Earth atmosphere number densities

The PROBA2 team is happy to announce the release of a new data product: the Earth atmosphere O+N2 number density profiles. These profiles are derived from solar occultation measurements by LYRA and are available at /lyra/data/EarthAtmosphere/. They are produced daily from beginning of December till end of January and are based on the backup unit (unit 3) measurements to limit the impact of instrumental degradation.

LYRA observes a strong solar flare in its Herzberg channel!

Big news in solar physics land: the sun produced a series of strong solar flares in the past week. On September 6, 2017, an X9.3 flare occurred in NOAA AR 12673 around 12:00 UT and was preceded by many other significant flares, including an X2.2 flare around 09:00 UT.
