Analysis of Flare Occurring Based on Sunspot Changing Patterns Using Zurich Method in February – April 2022 at the Astronomy Laboratory of Physics FMIPA State University of Malang

The star closest to our Earth is the sun with an average distance of 149,680,000 km. plasma a very high temperature. most easily observed solar activity from are sunspots and flares, where flares on can affect Earth’s atmosphere. Therefore this, research was carried out in February - April 2022 at Laboratory Astronomy Physics, State University Malang geographical location 07° 57’ 39” South Latitude, 112° 37’ 9.2” East Longitude, 7.9607° North Latitude altitude 465 meters using Celestron telescope. This study aims determine pattern changes until occurrence flare, find how flare. used descriptive approach based daily data that had been observed. In classifying sunspots, Zurich method used. development obtained shows sunspot patterns influence occur surface such as satellite damage auroras reported by NASA show flare sun. Based analysis classification, it classes C, D, E, F. these be seen news released NOAA. It concluded do not always large class classifications. However, small able produce
