PROBA2 data processing to be paused on June 24 - newly calibrated data will be published!

The PROBA2 team continuously works on improving the LYRA and SWAP data: the calibration routines for both instruments are updated regularly, and the latest version is always available, for example through SolarSoft.

Ninth Call for PROBA2 Guest Investigator Program - Extended

The PROBA2 PI-team welcomes research proposals for the ninth round of its Guest Investigator program for research based on SWAP and LYRA data analysis by scientists outside the SWAP and LYRA PI-teams. We encourage in particular early-career post-docs and PhD students to apply, although more senior guest investigators' proposals are also welcome.

Mercury Transit 2019

Mercury as it approaches the solar disk

All SWAP Images Available from the Mercury Transit on November 11 2019.

In preparation for the 2019 Mercury transit, the PROBA2 team have made a high cadence image campaign throughout the day. A movie made with all the SWAP data is shown below. All of our SWAP data products for this Mercury transit are now available here.

PROBA2 sees a Partial Eclipse on July 2, 2019

On July 2, 2019 the so-called Great South American Eclipse took place. The total eclipse path ran over parts of Chile and Argentina, where the Moon was seen to move in front of the Sun and blocked the sunlight out completely.

Evolution of a Coronal Cavity using SWAP, AIA, EUVI and LASCO data

The image on the right shows a coronal cavity observed by PROBA2/SWAP along with its associated filament as seen in SDO/AIA data. Coronal cavities are believed to be the low-density cross sections of magnetic flux ropes.

Synoptic Images of the Sun

Synoptic Image of the SunA synoptic map (or a latitude-time map) of the Sun shows the evolution of the Sun over a given period of time in a single image. The PROBA2 team have created a synoptic map of the Sun for whole Carrington Rotations.

PROBA2 Science Working Team Meeting 17

The PROBA2 team is pleased to announce the 17th PROBA2 Science Working Team (SWT) meeting, which will be held on Tuesday November 13, 2018 at the Royal Observatory of Belgium, between 15:30 - 17:30 local time (i.e. CET) in the Nadir room.

Solar Polar Images of the Sun

The solar poles are relatively unexplored regions of the solar atmosphere, this is due to a lack of satellites that have travelled over and through them. In this article we briefly explore how we can use current instrumentation to generate artificial polar images, and what might be learnt from studying the solar poles.
