WebSep 15, 2014 · 12. There is no simple conversion, it depends on the wavelength or color of the light. However, for the sun there is an approximate conversion of 0.0079 W/m 2 per Lux. To plug in numbers as an example: if we read 75,000 Lux on a light sensor, we convert that reading to W/m 2 as follows: 75, 000 × 0.0079 = 590 W/m 2. WebA solar radiation storm (also known as a Solar Proton Event or SPE) occurs often after major eruptions on the Sun when protons get launched at incredibly high speeds, sometimes up to several 10.000 km/s. These radiation storms can bridge the Sun-Earth distance in as little time as 30 minutes and last for multiple days.
