New Delhi: Hel1OS, attached to Aditya L-1 solar mission by ISRO has captured the first high-energy X-ray glimpse of solar flares. ISRO shared on X that the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) spectrometer on board has recorded the impulsive phase of solar flares, during its first observation period from October 29.
ISRO explained that a solar flare is a sudden brightening of the solar atmosphere. “Flares produce enhanced emission in all wavelengths across the electromagnetic spectrum – radio, optical, UV, soft X-rays, hard X-rays and gamma-rays.”
ISRO wrote, “Commissioned on October 27, 2023, HEL1OS is currently undergoing fine-tuning of thresholds and calibration operations. The instrument is set to monitor the Sun’s high-energy X-ray activity with fast timing and high-resolution spectra.”

HEL1OS was developed by the Space Astronomy Group of the U R Rao Satellite Centre, ISRO, Bengaluru.
Aditya-L1 spacecraft is designed to provide remote observations of the solar corona and in-situ observations of the solar wind at L1 (Sun-Earth Lagrangian point) at a distance of around 1.5 million kilometres from the Earth.
It is India’s first dedicated space mission for observations of the Sun.
