Aditya-L1 solar mission: HEL1OS captures first high-energy X-ray glimpse of solar flares

The Indian Space Research Organisation (ISRO) on Tuesday confirmed that the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) on board Aditya-L1 has recorded the impulsive phase of solar flares.

During its first observation period from approximately 12:00 to 22:00 UT on October 29, 2023, the High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) on board Aditya-L1 has recorded the impulsive phase of solar flares, ISRO said in a post on X.




"The recorded data is consistent with the X-ray light curves provided by NOAA's GOES," ISRO added.

"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,: the post further read.

With the help of HEL1OS data, researchers can study explosive energy release and electron acceleration during impulsive phases of solar flares.

HEL1OS was developed by the Space Astronomy Group of the U. R. Rao Satellite Centre, ISRO, Bengaluru.
