What is A multiwavelength study of the Sunspot of active region which leads to X 17 solar flare about?

## Abstract This paper focuses on the study of active region (AR) 486 from the 171 Å wavelength in conjunction with solar radio burst data from the e-CALLISTO. This active region produced quite a strong solar flare with the X 17 class on 28^th^ October 2003. The intense solar flare was detected by the CALLISTO system as the type III solar burst. Another data for this study were collected from the online database of Solar Monitor and Space Weather Live website where they provided the data from NOAA and SDO/AIA publicly. The study of the solar flare event was done by observing the sunspot for the past six days to see the changes in the magnetic field of the active region 486 and compared it to the solar radio data for the nature of the solar flares. The active region 486 alone had a sunspot number of 74 which is quite high, hence it produced a flare with the solar wind speed of 800 km/s and a solar radio burst type III with the storm type. The frequency drift rate for the solar burst was 2.15 MHz/s which proved that this type III is a fast drift burst. It was also recorded that the coronal mass ejection followed this solar flare event with the speed of nearly 2000 km/s and directed t
