PROBA2 helps provide Venus space weather reports

PROBA2 space weather exampleAfter eight years in orbit, ESA’s Venus Express has completed routine science observations and is preparing for decomissioning by aerobraking into Venus' atmosphere; Throughout this maneuver the Space Weather Coordination Centre, aided by PROBA2 observations, will be providing regular space-weather reports for Venus!

PROBA2 Guest Investigator 5th Call Results

We are pleased to announce that the PROBA2 Science Working Team has selected 6 proposals for the 2014 Guest Investigator Program.

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.

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.

SWAP & LYRA capture an X4.9 flare

On February 25th, early in the morning, the 'returning' active regions AR11967 (now called AR11990), generated an X4.9 flare, the strongest flare in 2014. Both LYRA and SWAP on-board PROBA2 witnessed the event.

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.

MYSTERIES DEEPEN AS COMET ISON FAILS TO MAKE LONG ANTICIPATED APPEARANCE

MYSTERIES DEEPEN AS COMET ISON FAILS TO MAKE LONG ANTICIPATED APPEARANCE

The long-awaited and much-hyped comet ISON surprised astronomers and solar physicists when it mysteriously failed to appear in images from extreme-ultraviolet (EUV) solar telescopes on Thursday. The SWAP solar telescope, on board the Belgium-based ESA mission PROBA2, conducted an extraordinary campaign to image ISON, but failed to detect any sign of the unusual comet.
