SWAP/PROBA2 Observes Partial Solar Eclipse

On Thursday, October 23, 2014, SWAP, an ultraviolet telescope onboard PROBA2, observed three separate passages through the Moon's shadow, meaning it witnessed three partial solar eclipses in a single day!

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.

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.
