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.

 

P2SC server maintenance May 7, 2025

Update: the server migration was succesfully finished and all missing data were processed on May 8. The P2SC is up an running again.

A major server upgrade is planned for the PROBA2 Science Center. Now that the preparations are complete, we are planning a migration to the new server on May 7, 2025, which will have strong implications on the services provided by the P2SC.

Another solar eclipse coming up for PROBA-2

The PROBA-2 team is preparing for the next eclipse. Upcoming March 29, the solar instruments onboard will observe their 35th eclipse, which is quite rare for solar instruments like LYRA and SWAP.

Preparing for Comet C/2024 S1 (ATLAS)

UPDATE: the comet desintegrated before it reached the SWAP field-of-view.

A sungrazer comet is racing towards its close encouter with the solar corona. As part of a massive, world-wide campaign to study the comet, the SWAP imager will attempt to capture images of the comet as it passes the sun. If SWAP is able to see the comet, the observations could yield important information both about comets, the solar corona, and the sun's complex magnetic field.

Exceptional detection of an X9.0 flare by PROBA2

On October 3, the Sun unleashed its most powerful eruption since 2017: a solar flare classified as X9.0 on the GOES scale, accompanied by a significant coronal mass ejection. We also observed a signal related to this flare in the Herzberg channel which is extremely rare.

The October 2 solar eclipse

After all the excitement surrounding the Great American Eclipse earlier this year, it is easy to forget that another one of these mesmerising was scheduled for the fall. The PROBA2 team prepared for special observations on October 2 when the instruments onboard had a first row seat of the eclipse.

Call for Guest Investigators

Once more, the solar physics team of the Royal Observatory of Belgium invites external researchers to join in the data exploitation of its space telescopes on the PROBA2 microsatellite (SWAP, LYRA) and on Solar Orbiter (EUI).

The great eclipse

April 8,  2024. A date that has been highlighted in many calendars for months. It is the day of the Great American Eclipse, as it is now called. A total eclipse during which the Moon’s shadow will cover large parts of Mexico, the USA and Canada. In fact, weather permitting, all of Noth America will witness at least a partial eclipse on that day.

Annular eclipse On October 14, 2023

On Saturday, October 14, an annular solar eclipse crossed North, Central, and South America. Due to its fast polar orbit, the PROBA2 satellite did not cross the eclipse path, but instead observed several partial eclipses.

New Guest Investigator Call: visit the EUI and SWAP/LYRA PI teams in Brussels in 2024!

The EUI and SWAP/LYRA PI teams welcome research proposals for the 2024 round of its Guest Investigator Program for research based on EUI, SWAP or LYRA data analysis by scientists outside the PI teams.
