The Solar Observatory was used to observe the photosphere of the sun. The main focus to observer the photosphere are the sunspots and prominences that develop on the surface. These phenomenon can lead to Coronal Mass Ejections (CME’s). After taking pictures and analyzing them, there was only one day that had any activity on the photosphere. It was concluded that the sun is at it’s solar minima. This means that there is little to zero activity on the suns photosphere. With this, and more data over an extended period of time, it is possible to calculate a solar cycle.
