Twelve years ago today, on 14 december 2009, the SWAP EUV telescope onboard the PROBA2 satellite 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 satellite.

While the penguins were gazing at the total eclipse on December 4, the instruments onboard the PROBA2 satellite worked overtime to image and measure not one, but four passages of the moon in front of the sun. One of these occultations was nearly total for the SWAP EUV imager: as much as 96% of the solar disk was covered by the moon during the second passage

Scientists run the EUHFORIA computer programme to have a preview of the solar eclipse of December 4. A chance to check their calculations. Fingers crossed and certainly ask the penguins.
