Dear colleagues,


We are pleased to announce the first joint ISWI - SCOSTEP/COURSE online
seminar of 2026 by  *Prof. Dibyendu Chakrabarty,* scheduled for May 27th,
2026, at *14:00 UTC*.

*Title*: *Insights on solar wind and energetic particles based on Aditya-L1
measurements*
*Speaker*: *Prof. Dibyendu Chakrabarty *
Space and Atmospheric Sciences Division of Physical Research Laboratory
(PRL), India

*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.
