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.

 

PROBA2 Science Working Team Meeting 16

The PROBA2 team is pleased to announce the 16th PROBA2 Science Working Team (SWT) meeting, which will be held on Monday August 6, 2018 at Royal Observatory of Belgium. A webex will be released soon. More details to follow.

SWAP and LYRA data gaps expected on May 6, 2018

UPDATE: the scheduled maintenance of PROBA2 took longer than foreseen and the solar instruments were not yet turned on. We now expect that the data gaps for SWAP and LYRA will continue until May 7.

The SWAP and LYRA instruments will be turned off during the morning of May 6, 2018 due to a scheduled maintenance of the PROBA2 spacecraft.

LYRA and SWAP will stop acquiring data around 23:40 UT on May 5 and, if all goes as planned, will resume their normal operations at 06:30 UT on May 6. 

 

PROBA2 Partial Eclipse Observations - 15-Feb-2018

A partial solar eclipse was visible on 2018 February 15, in the southern part of South America, including many locations in Argentina, Chile, Paraguay, and Uruguay, as well as in Antarctica. The eclipse was visible from some areas of the Atlantic and Pacific Oceans as well. 

SWAP and LYRA data gaps

On Friday December 8, an unexpected reboot of the PROBA2 spacecraft occurred. This caused the LYRA and SWAP instruments to turn off, leading to a gap in their data flow.

The LYRA operations were restarted successfully on the next day and the instrument has been delivering measurements since 18:53 UT on December 9. 

PROBA2 Science Working Team Meeting 15

The PROBA2 team is pleased to announce the 15th PROBA2 Science Working Team (SWT) meeting, which will be held on Tuesday November 28, 2017 from 13:00 to 14:30 central european time at the European Space Weather Week. The meeting will be held in the Stijnen room, where a small lunch is being offered.
 

Release of a new LYRA product: O+N₂ Earth atmosphere number densities

The PROBA2 team is happy to announce the release of a new data product: the Earth atmosphere O+N2 number density profiles. These profiles are derived from solar occultation measurements by LYRA and are available at /lyra/data/EarthAtmosphere/. They are produced daily from beginning of December till end of January and are based on the backup unit (unit 3) measurements to limit the impact of instrumental degradation.

LYRA observes a strong solar flare in its Herzberg channel!

Big news in solar physics land: the sun produced a series of strong solar flares in the past week. On September 6, 2017, an X9.3 flare occurred in NOAA AR 12673 around 12:00 UT and was preceded by many other significant flares, including an X2.2 flare around 09:00 UT.
