Variations in EUV Irradiance: Comparison between LYRA, ESP, and SWAP Integrated Flux

Poedts, Stefaan; Yalim, Mehmet Sarp

The Sun Watcher Using Active Pixel System Detector and Image Processing (SWAP) telescope and Large Yield Radiometer (LYRA) are the two Sun observation instruments on-board PROBA2. SWAP extreme ultraviolet images, if presented in terms of the integrated flux over solar disk, in general, correlate well with LYRA channel 2-4 (zirconium filter) and ch…
