End of March I have added a post about the (lack of) sunspot activity on the Sun.
Solar cycle 24 was so slow in starting, that some scientist got worried.
What is the present situation? See the graph below. Four more data points became available (April-July). The graph comes from http://solarcycle24.com/sunspots.htm
The red curve is a prediction, made in 2009.
The authors write:
“If our prediction is correct, Solar Cycle 24 will have a peak sunspot number of 90, the lowest of any cycle since 1928 when Solar Cycle 16 peaked at 78 ”
When you look at the latest data points, the prediction seems too high, it should be adjusted.
Actually this has been done last month, see below. This new prediction gives an even lower maximum, below 70 !!
If this prediction comes true, we even have to go back to solar cycle 14, with a peak value of 64, in 1906. Click here for the list of solar cycles.
You can bet on it that solar scientists are following the development with great interest.
I will give you another update in a couple of months.
