Welcome to the PROBA2 Science Center

Comet ISON raced past the Sun on November 28, but left no clues about its structure — or the structure of the solar corona — for extreme-ultraviolet (EUV) telescopes like SWAP that had been turned towards the unique comet in the hope of capturing images of its passage through perihelion.

The PROBA2 team is proud to present the PROBA2 Holiday Countdown Calendar! One day at a time you will discover highlights of the PROBA2 satellite and the Sun!

In just a few hours, Comet ISON will whip past the surface of the sun at hundreds of kilometers per second, and PROBA2 is waiting to capture its passage through perihelion.

PROBA2 Christmas Countdown Calendar

Three partial solar eclipses were observed  by PROBA-2 as it moved in and out of the Moon’s shadow during the 03-Nov-2013 ‘hybrid’ solar eclipse.

A hybrid eclipse is comprised of a total solar eclipse and an ‘annular eclipse’, depending on an observer’s viewing location on Earth.

During a total solar eclipse, the Moon moves between the Sun and the Earth, their alignment and separation are such that the much closer Moon appears large enough to block out the light from the much more distant Sun.

We are pleased to announce that the PROBA2 Science Working Team has selected 7 proposals for the 2013 Guest Investigator Program.

The Dual Segmented Langmuir Probe (DSLP) experiment on board PROBA2 operates in combination with SWAP and LYRA providing remote observations of solar activity with direct in-situ measurements of basic plasma properties in the dawn and dusk sectors of the upper terrestrial ionosphere.

Over a period of five days, from Wednesday 24th 13:05 until Monday 29th 13:45, PROBA2 made off-point observations (not Sun centered) to allow the SWAP imager to observe a large on-disk filament. The filament evolved towards the West limb and it was estimated to reach the limb on Friday/Saturday.
