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.

 

Special observation campaign with SWAP

The PROBA2 team is planning a special observation campaign in collaboration with the Solar Orbiter and Parker Solar Probe teams next week.

The Sun in 2020

 
 

December 14, eclipse time!

On Monday December 14, a total solar eclipse, the last eclipse of 2020, was visible from parts of Chile and Argentina. Weather permitting, some locations in South America, south-west Africa, and Antarctica saw the partial phase of this eclipse, as did the instruments onboard PROBA2.

Long-term evolution of the solar corona using PROBA2 data

We studied the evolution of the solar corona observed throughout solar cycle 24 (from 2010 to 2019), by using PROBA2/SWAP images, PROBA2/LYRA irradiance time series, and the latest version of the International Sunspot Number (ISN) dataset.
 

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.
