College Haldwani (Nainital), Uttarakhand, India Department of Physics, D.S.B. Campus, Kumaun University Nainital, Uttarakhand, India A statistical study of Total Column Ozone (TCO) with Different solar activity features (DSAF), viz. sunspot number, solar flare, solar active prominences for a Northern station Shimla (31°10'N, 77°17'E) and an Eastern station Imphal (24°82'N, 93°94'E) of India is presented using 11 years (2004-2016) of data. In this study we have compared the trends in TCO with DSAF annually as well as for seasonal months. Our study shows a negative correlation between TCO and DSAF. A negative correlation suggests that there is decrease in Ozone concentration during the given time period with solar activity. http://pubs.sciepub.com/aees/8/6/16/aees-8-6-16.pdf total column ozone sunspot number solar flare solar active prominences
