PROBA2 eclipse season 2010 has started

The eclipse season has started for PROBA2, although not in all channels/instruments yet. Every winter, the solar (E/X)UV signals SWAP and LYRA observe are obscured by the Earth and Earth’s atmosphere. Earlier this week, we saw the first effects of the filtering by the Earth’s atmosphere in the two short-wavelength LYRA channels: Al and Zr. The long wavelength channels, neither SWAP show any effect yet but this will come very soon, later this week.
