Recent Improvements to SWAP Image Calibration

Frequent users of SWAP data or watchers of SWAP movies may have noticed some unusual behavior in these images and movies in the last few days. We've been improving the spatial calibration of the data and our tests resulted in a few unusual images, but now that everything is finished you'll notice SWAP images look better and are easier to use than ever before.

Fifth Call for PROBA2 Guest Investigator Program, extension of the deadline for proposal submission to 15 June 2014

SWAPLYRADue to the interest in the PROBA2 Guest Investigator Program and taking into consideration the extended holidays in several countries, the P2SC Team has decided to extend the proposal deadline for the PROBA2 Guest Investigator Program to 15 June 2014

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.
