Solar X-ray Flux Monitor to monitor solar x-ray flares.


Solar X-ray Flux Monitor. In-orbit demonstration of the technology using reduced resources in preparation for a fully space-qualified version some years from now. XFM is needed for the detection of solar X-ray flares; one of the most energetic phenomena on the Sun giving rise to Space Weather phenomena in the heliosphere up to the Earth’s distance and beyond.


The SUNSTORM satellite’s XFM instrument is capable of measuring high-energy electrons and detected even a 10 times higher electron flow values than normally in the SUNSTORM satellite’s 540 km high orbit well in advance of the geomagnetic storm which hit the Starlinks. In short, the satellite’s measurements showed that the eruption in question was both exceptionally long-lasting and clearly more energetic than normally. These properties are not detected with currently used instruments. This added information would have been crucial in predicting the magnitude of the upcoming geomagnetic storm.
