About the PROBA2 Science Center


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.

Automated SWAP Carrington Rotation Movies Online

Mini Carrington Rotation ImageThe PROBA2 team is proud to present fully automated updated Carrington rotation movies. A Carrington Rotation is a period of time chosen to represent one rotation of the Sun, allowing the comparison of features such as sunspot groups or active regions (a description of active regions can be found here). A period of 27.28 days was chosen to represent a single rotation that largely resembles the recurrence time of features near the equator.
The rotation period was initially conceived by Richard Carrington, when he determined the rotation rate of low latitude sunspots. Carrington determined a rotation rate of 25.38 days relative to background stars (sidereal rotation period). However, due to the Earths orbit, this is perceived as 27.28 days from the Earth. Each rotation of the Sun is assigned a Carrington Rotation Number, starting from 09-Nov-1853. That number has now reached 2194 at time of writing (13-Jun-2017); More information can be found here.

The first solar eclipse of 2017

On February 26th, lucky observers along the eclipse path in Chile, Argentina, Angola, Zambia and The Democratic Republic of the Congo have been able to witness an annular eclipse.
