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 data flow interrupted

As a result of P2SC system upgrades that were performed on November 9, the processing of LYRA and SWAP data is currently interrupted.

Both instruments are in good health and still collecting data. This data is being received from the satellite and stored securely on ground.

We will process all archives as soon as possible and put the resulting files online when they are ready.

Solar eclipse on October 25, 2022

The second solar eclipse of the year has occurred! On October 25 the Moon passed in front of the Sun once more. This was a special eclipse to us, as it was visible as a partial eclipse from PROBA2’s home country, Belgium. 

PROBA2 in the spotlight at the Space Pole Open Days

On September 24. and 25, 2022 the Space Pole in Brussels organized its Open Days. 

SWAP and LYRA Calibration Campaigns from September 5 to 8, 2022

We would like to point out to all PROBA2 data users that there were gaps in the regular science data streams from SWAP and LYRA from 2022-09-05 to 2022-09-08 due to special calibration campaigns. 
 
LYRA performed a long calibration campaign starting at 2022-09-06 at 14:30 UT using units 2 and 3.
 

First eclipse of 2022

Solar enthusiasts in southern South America (mostly Chile, Argentina, and Uruguay), as well as those in parts of Antarctica, and sailing on the Pacific and Atlantic Oceans had to get their eclipse glasses out! While the Sun was setting in the west, they were able to observe a partial solar eclipse in the evening of April 30.

12 years of successful LYRA observations

12 years ago today, on 6 January 2010, the doors of the LYRA instrument were opened for the first time. The observation of LYRA's first Lyman-alpha flare paved the way for much interesting science.

Celebrating SWAP's first glimpse of the Sun

Twelve years ago today, on 14 december 2009, SWAP laid its eye on the Sun for the first time. After the nerve-racking procedure of opening the instrument door and taking this first image, PROBA2 operators and scientists waited impatiently for this first image to be downloaded from the PROBA2 satellite.

December 4, 2021: Antarctic Solar Eclipse

Let’s hope the penguins have their eclipse glasses ready. They will form most of the crowd in the Antarctic that will be able to witness a total solar eclipse on December 4. Fortunately, spectators in parts of southern Africa, South Australia, New Zealand and South America will see a partial solar eclipse, if the weather cooperates of course.

First X-flare in nearly 4 years!

Even though the new solar cycle 25 officially started in December 2019 already, solar physicists have had to wait for a long time for clear signs that solar activity is picking up. On July 3rd, 2021 they finally got to witness a strong solar flare.
