2026 LYRA Flare List

• This list uses the "G16" (formerly the "G14" and "G15") X-ray entries from the "Edited Events" lists of the NOAA Space Weather Prediction Center.
• The purpose of the list is to get an overview of the flares that LYRA observes and relate them to class, begin, max, etc. according to GOES.
• In the daily images (follow links below), the flares are marked at the top of the LYRA Zr-channel curve, with event number and class corresponding to their temporal "begin".
• Images of intervals around each flare (1h before, 2h after) are linked to a list below this curve (follow event links), given that LYRA was observing during this interval.
• In the flare images, event number and class are again marked at the top, corresponding to their "begin", while the GOES maximum is marked with a short vertical line. These images contain all four LYRA channels, plus one GOES channel.
• From November to January, PROBA2 experiences "eclipse season". For several minutes during each orbit, the solar disk is occulted by the Earth, and the observed irradiances decrease to dark-current levels - thus LYRA flares may be (partially) hidden.
• Additional information can be found at the PROBA2 website on the LYRA daily quicklook page or on the LYRA 3day quicklook page.
