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.

 

Eclipse challenge

Solar eclipses have fascinated people since ancient times and also today many people will gaze up in wonder to witness the spectacle of a solar eclipse. In parts of Russia and Canada one can witness it as an annular eclipse. From Belgium, today's eclipse will be partial, when the Moon will seemingly take a bite out of the top of the Sun around midday (maximum at 12:19 local time). 

Partial eclipse in Belgium - 10 June 2021

On 10 June 2021, the Belgian PROBA2 Science Center team will be able to witness a solar eclipse with their own eyes (weather permitting). In parts of Russia and Canada one can witness this event as an even more spectacular annular eclipse.

Between 2 and 5 solar eclipses occur every year.

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.

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.
