#29 Title: Insights on solar wind and energetic particles based on Aditya-L1 measurements
Speaker: Prof. Dibyendu Chakrabarty
Affiliation: Space and Atmospheric Sciences Division of Physical Research Laboratory (PRL), India
Date and Time: May 27th, 2026, at 14:00 UTC

Abstract: Aditya-L1 is the first dedicated solar observatory launched by India in 2023. The instruments in this mission are designed to probe the Sun in visible, infrared, near ultra-violet, soft and hard X-rays as well as equipped to measure the solar wind, energetic particles and interplanetary magnetic field. There are four remote sensing and three in situ experiments on board Aditya-L1. Aditya Solar wind Particle EXperiment (ASPEX) in one of the three in-situ experiments that measures solar wind and also energetic particles in direction-resolved manner. ASPEX consists of two spectrometers – Solar wind Ion Spectrometer (SWIS) and SupraThermal and Energetic Particle Spectrometer (STEPS). While SWIS measures the solar wind and the suprathermal ions, STEPS measures the energetic particles.
 
The data from ASPEX have been extensively validated with the measurements from other international missions and at present, the solar wind and energetic particle fluxes as well as solar wind bulk parameters (like density, velocity, temperature etc.) are being regularly posted in near real time (latency of 2-3 days) to the Indian Space Science Data Centre (ISSDC) website for the use of the scientific community. In this talk, some of the recent science results pertaining to solar wind and energetic particles will be discussed to underline the quality of the data that ASPEX has been producing. Therefore, this is not surprising that scientific community is getting increasingly interested in ASPEX data to understand the impact of space weather on the terrestrial magnetosphere-ionosphere-thermosphere system. Some of these results will be discussed in this seminar.
