An analysis of short term variability sunspot (January-September 2010) and correlation between sunspot area / Fatimatun Nur Zainal Ulum.

The Sun is one of the salient features in our galaxy which emit energies in term of light and radiations. For the explanations, the energies created within the Sun are somehow yet to be determined in more detail and precise explanation. The Sun is full of many mysterious phenomena that need to be revealed. One of the phenomena that are studied in this project is sunspots. There are some association between sunspots and other hazardous effects it may have on earth as for example solar flares and Coronal Mass Ejection (CMEs). Also, sunspots were said to have some effects on earth climate upon the creation of solar flares and CMEs. The methodology in this project is using the radio telescope and helio v3.2 software to take the data of sunspot number and sunspot area from January 2010 until September 2010. The Sun was found to be most active and least active according to the sunspot number and the sunspot area. At the end of this project, the highest total number of sunspot was recorded in August which is 875 while the lowest total number of sunspot was recorded in April which is 336. In this project, the correlations between sunspot number and sunspot area have been observed and they not precisely linear correlated. Furthermore, based on sunspot number and sunspot area we can conclude that the Sun now is in a minimum 23r cycle since the sunspot numbers and sunspot area nowadays are low.
