career in solar Physics. The technical session on the first day was titled 'Aditya L1 mission', and Durgesh Tripathi, IUCAA, Pune, delivered a lecture on 'Solar Ultraviolet Imaging Telescope (SUIT) and other payloads on board Aditya-L1. He provided the technical details about the first Indian Solar Mission, “Aditya L1,” by ISRO and encouraged undergraduate and postgraduate students to pursue a career inSolar Physics. The second lecture by Ram Kishor, Central University of Rajasthan, Ajmer, was about the existence analysis of Lagrange Point- L1, stability analysis and possible application in different space missions. Nishant Singh, IUCAA, Pune, also gave a talk and interacted with young students attending the workshop. He discussed the fundamentals of magnetohydrodynamics, a branch of physics that deals with magnetised plasma, e.g., the Sun. The workshop began with an inauguration ceremony on 04 December 2023 chaired by Bechan Sharma, Dean, Faculty of Science, University of Allahabad and Durgesh Tripathi, IUCAA, Pune, as the Chief Guest. The inaugural function began with a welcome of the dignitaries and the lighting of the lamp, followed by Saraswati Vandana. V. K. Tiwari, Head, Physics depar tment , gave a summar y and objectives of theworkshop. Abhishek Srivastava, IIT, BHU, began the technical session on the second day. He covered various topics, such as solar flares, CMEs, magnetic reconnection, Alfven waves, etc. He gave an overview of both theory and observations. He discussed one of the most important problems of solar physics, namely, the solar coronal heating problem, which remains amystery. In his talk, Vaibhav Pant, ARIES, Nainital elaborated on CMEs evolution kinematics space weather. He emphasised the importance of studying the Sun and the role of Aditya-L1 in this regard. He provides detailed observations about the Coronal Mass Ejections (CMEs) from the launch of SOHO in 1996. Vaibhav Pant explained the CMEs as the clouds of plasma and magnetic field that are ejected from the a tmo s p h e r e o f t h e S u n i n t o t h e heliosphere, with speeds ranging between 400-2000 km/s. CMEs are mostly associated with the eruption of active region's prominences or quiescent prominences. CMEs are the drivers of Spaceweather.
