NEW DELHI: The X-ray spectrometer, HEL1OS, attached to Aditya-L1 spacecraft by ISRO for its maiden solar mission, captured the first high-energy X-ray glimpse of solar flares. In its update, ISRO on Tuesday noted that the spectrometer on board Aditya-L1 has recorded the impulsive phase of solar flares, during its first observation period from approximately October 29, 2023. A solar flare is a sudden brightening of the solar atmosphere. Flares produce enhanced emission in all wavelengths across the electromagnetic spectrum. Commissioned on October 27, the HEL1OS X-ray spectrometer is currently undergoing fine-tuning of thresholds and calibration operations.
