LYRA Science Goals

Flares Detection and Analysis Solar flares are one of the most energetic phenomena in the solar system. During these events, particles can be heated to millions of degrees and ejected in the solar atmosphere. These events appear in radiometer time series as an increase of the solar irradiance, especially in X and UV ranges. Understanding those events is a "hot" science topic. LYRA benefits of a very favorable acquisition cadence (up to 100Hz), while most of the solar instruments acquire (...) - 10. LYRA

LYRA instrument

Instrument overview LYRA is composed of three units, each of them constituted of the same four channels: the 120-123 nm Lyman-α channel, the 200-220 nm Herzberg continuum channel, the 17-80 nm Aluminium filter channel, including He II at 30.4 nm, the 6-20 nm Zirconium filter channel. The difference between units lies in the detectors – filters combinations that have been chosen to achieve these band passes. The nominal unit is fully provided with pioneering diamond detectors and will (...) - 10. LYRA
