PROBA2 Views a Total Solar Eclipse - 2015

Updated (25 March 2015): On 2015 March 20, PROBA2 observed a total solar eclipse — twice! The spacecraft's orbit carried it through the darkest parts of the Moon's shadow two times, first between 08:28 and 08:53 UT and again between 10:24 and 10:50 UT. Eclipse chasers, scientists, media and members of the general public have been following our data closely, so we are collecting all of our results and data products in one place for quick access.

SWAP, an Extreme-Ultraviolet solar telescope, observes the solar corona in a passband centered on 17.4 nm. The structures we see in SWAP images have a temperature of approximately 1 million degrees. LYRA, an X-ray/Ultraviolet radiometer observes the total incoming light levels from the Sun in several wavelength bands.

More information about these instruments is available here: SWAP | LYRA.

Exciting press for SWAP

SWAP was recently featured in two ESA stories! SWAP took this week’s Space Science Image of the Week. The image is from 25 July 2014 and is reproduced below. It shows a large coronal-fan structure on the left side of the Sun.
 

Giving SWAP images a make over - novel image processing techniques

In 2014 Morgan and Druckmuller introduced a new image processing technique to reveal information at the finest scales of solar images, whilst maintaining enough of the larger-scale information to provide context.

A Monster Active Region

Active Region 12209, the same region that gave us a half-dozen X-class solar flares during its last rotation across the Sun, is returning. Currently on the east limb, it is a spectacular sight for SWAP, the EUV imager on-board PROBA2.

Happy Birthday PROBA2!

On November 2, 2009, a Russian Rockot launch vehicle carried the PROBA2 spacecraft into orbit. In the five years since its launch, PROBA2, whose scientific mission is led by scientists at the Royal Observatory of Belgium in Brussels, has completed more than 25,000 trips — more than a billion kilometers — around the Earth, captured more than one million images of the Sun, and witnessed more than 6,000 solar flares.

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
