Update of LYRA level2

The calibration of LYRA data (level 2) has been updated on December 31 2016 00:00:00 to take into account new information about the evolution of dark current, as well as the result of the last calibration campaigns. This update currently results in a small amplitude jump in the timeseries. This jump should disappear the next time the data will be reprocessed, in a few months.

 

Solstice Eclipse

On June 21, 2020 an annular eclipse took place, reaching its maximum at 06:40 UTC. The annular phase of this solar eclipse was visible from parts of Africa (including the Central African Republic, Congo, and Ethiopia), south of Pakistan and northern India, and China.

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.

PROBA2 sees a Partial Eclipse on December 26, 2019

On December 26, 2019 an annular solar eclipse took place. The eclipse path ran over multiple countries including parts of India, Indonesia and Malaysia and many nearby countries could also see a partial eclipse. This eclipse was not visible from Belgium, but we were able to observe it as a partial solar eclipse with the Belgian PROBA2 satellite. The satellite orbits the Earth so quickly that it was able to observe the eclipse more than once before the Moon had completely traversed the solar disk.

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.
