Isro has announced that its High-Energy L1 Orbiting X-ray Spectrometer instrument on the Aditya-L1 solar space observatory has successfully recorded impulsive phase of solar flares. The data collected by HEL1OS is consistent with the X-ray light curves provided by the US’ National Oceanic and Atmospheric Administration. The instrument is set to monitor the Sun’s high-energy X-ray activity and will enable researchers to study explosive energy release and electron acceleration during solar flares.
