<p class="spip">LYRA will monitor the solar irradiance in four carefully selected UV passbands. The channels have been chosen for their relevance to Solar Physics, Aeronomy, and Space Weather: 1/ the 200-220 nm Herzberg continuum range, 2/ Lyman-alpha (121.6 nm), 3/ Aluminium filter EUV channel (17-70 nm) covering He II at 30.4 nm, and 4/ Zirconium filter XUV channel (1-20 nm), where solar variability is highest.</p>

<p class="spip">The LYRA diamond detectors are designed and fabricated at IMOMEC, Belgium with the collaboration of the National Institute for Materials Science (NIMS), Japan and the Institut d&#8217;Electronique, de Microélectronique et de Nanotechnologie (IEMN), France. The single pixel devices are MSM structures and PiN diodes, depending on the LYRA channel.</p>

<p class="spip">SWAP (Sun Watcher using APS and image Processing), a solar EUV imaging telescope, will operate on PROBA2 as well. 
LYRA demonstrates technologies important for future ESA missions such as e.g. Solar Orbiter. The sensor devices are promising for other applications as well: Earth remote sensing, ozone hole monitoring, EUV lithography, among others.</p>
