Our Sun next solar cycle started on Sep2020.
Solar cycle happen every 11 years. This solar cycle calculated based on minimum and maximum solar activity. During this period the sun flip the magnetic field from north to south so these leads to heavy solar activity and when sun reaches it peak activity we can see many Sun spots.
Sunspots are usually black in color in visible light, but when we see the Sun in ultra violet wavelength we can see the intensive magnetic field activity .
Why we need to monitor the Solar cycle?
During the Sun’s peak active period large amount of coronal mass ejection will happen , so during this time it will directly affect the earth and heats up the earth atmosphere that will cause damage to electric transmission , pipelines ,communication towers and satellites. Also this huge radiation affect the astronauts in space station.
So Continuous Monitoring will help us to understand pattern of the peak solar activity , Using that we can prevent the electronic equipment by turning off the device during the peak solar period. Also we warn the astronaut not to do the space walk during that period.
Usually peak solar activity happens in middle of the solar cycle. Last one happen at 2012.

note: Last major corona mass ejection happen at 2012 and we detected this event only after 9 days from the event.
