Overview: The sun is blank today for the 10th straight day and it has been without sunspots this year more than half the time as the current solar cycle heads towards the next solar minimum. Solar cycle 24 is currently on pace to be the weakest sunspot cycle with the fewest sunspots since cycle 14 peaked in February 1906. Solar cycle 24 continues a recent trend of weakening solar cycles which began with solar cycle 21 that peaked around 1980.
The last time the sun was this blank in a given year on a percentage basis was 2009 during the last solar minimum when 71{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the time was spotless. That last solar minimum actually reached a nadir in 2008 when an astounding 73{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the year featured a spotless sun – the most spotless days in a given year since 1913.
