SWAP LYRA Calibration between 2014-Mar-26 09:00 UT and 2014-Mar-27 19:40 UT

There will be no regular science data from SWAP between about 2014-Mar-26 09:00 UT and 2014-Mar-27 20:00 UT due to a calibration event.

The Big Wave!

At around 14:00 on March 5th 2014, SWAP, the EUV imager on PROBA2, observed a wave travelling over the solar North pole. The wave was probably generated during a strong eruption on the Northern backside of the Sun.

Using the SpoCA segmentation suite to track long term variations in EUV observations

A recent paper by Verbeeck, C. et al. entitled "The SPoCA-suite: Software for extraction, characterization, and tracking of active regions and coronal holes on EUV images", in the journal Astronomy & Astrophysics, discusses a new software suite that can be used to track and segment different regions of the Sun from EUV images.

No Clues from Comet ISON

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.

PROBA2 Holiday Countdown Calendar

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!

PROBA2 waits for Comet ISON

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.

SWAP observes three partial solar eclipses

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.

PROBA2 Guest Investigator 4th Call Results

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

DSLP ionospheric on-line data archive

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.
