| KHAG L | No. 118 - APRIL 2019 | 10 National Workshop on Introduction to Solar Astrophysics (Astronomical Data Analysis Series) The National Workshop on Introduction to SolarAstrophysics was conducted at the Department of Physics, St. Xavier's College for Women, Aluva, during March 2 – 3, 2019. This workshop was the fourth in the series organised by the Academy of Physics Teachers (APT), Kerala, and was sponsored by IUCAA. Also, this was conducted under the Teaching Learning Centre in Astronomy and Astrophysics at IUCAA, of the Ministry of Human Resources Development, Government of India, under the Pandit Madan Mohan Malviya National Mission on Teachers and Teaching Scheme, to train teachers and students from various colleges in Kerala in data analysis in the field of Astrophysics. The workshop targeted young researchers, post-graduate students and teachers, and the participants registered included 33 students and 16 teachers and research scholars. Sheena Xavier (Head, Department of Physics) welcomed the resource persons and participants, and Sr. Stella (Vice Principal) inaugurated the workshop, which consisted of lectures in the mornings and hands-on sessions in the afternoons. The resource persons were: Durgesh Tripathi (IUCAA), Sreejith Padhinjatteri (IUCAA), Sargam Muley (IUCAA), andAveek Sarkar (PRL,Ahmedabad). During the morning sessions, Durgesh Tripathi, along with Aveek Sarkar covered the topics on various aspects of Sun, Solar Dynamo, Physics of Solar Atmosphere and upcoming Indian Solar Mission Project 'Aditya-L1'. In the afternoon sessions, there were Solar Data Analysis hands-on sessions, tackling simple projects using Solar Data. On the first day, Sreejith Padhinjatteri and SargamMuley introduced the Linux OS and Interactive Data Language (IDL) with its basic commands for handling the data analysis. Real solar observation data were taken from Solar Dynamics Observatory, and its analysis techniques were explained to the participants. On the second day afternoon session, the participants got an opportunity towork on Solar Data, i.e., sun spot number, solar flux, etc. over the period of ~ 100 years, etc. During the valedictory session, the participants gave their feed backs and suggestions. According to them, the workshop was well organized, and useful and helpful in their on-going research and projects. Participants also suggested to have long duration (minimum one week) of the programmes for better effectiveness, covering more data analysis and more advanced topics including research topics. The feedback received from them suggested that the conference was a great success and achieved its stated objectives. Durgesh Tripathi, Sujatha N. V. (St. Xavier's College), and Joe Jacob (Newman College, Thodupuzha) were the coordinators of theworkshop. National level Winter School in Astronomy, Astrophysics and Cosmology was organised during January 7 - 13, 2019, by the Department of Physics, Gauhati University (GU), Guwahati, and was sponsored by IUCAA. The objective was to discuss the current trends of research in theoretical and observational astrophysics and cosmology, and to train students of physics and astronomy, who would be potential participants in astrophysical studies in the new era of extremely large telescopes. The school was inaugurated by Mridul Hazarika (Vice Chancellor, GU). There were 30 student participants from the Universities of North-East India, Uttarakhand, Kolkata and Delhi. Winter School in Astronomy, Astrophysics and Cosmology The speakers were: Ganesh Srinivasan (RRI, Bengaluru), Ram Sagar (IIA, Bengaluru), Padmakar Singh Parihar (IIA, Bengaluru), Dhruba Jyoti Saikia (IUCAA), Asoke Kumar Sen (Assam University, Silchar), Brijesh Kumar (ARIES, Nanital), Sukanta Deb (Cotton University, Guwahati), Biman J. Medhi (GU), and Sanjeev Kalita (GU). Topics such as Physics of Stars, Multi-wavelength Astronomy, Astronomical Instrumentations, Star Formation, Solar System, General Relativity and Black Holes, Quasars, Cosmology, Variable Stars and Light Curves, Astronomical Data Analysis, etc. were discussed. Sanjeev Kalita, Biman J Medhi, and Ranjeev Misra (IUCAA) were the coordinators
