Sunspot Number Progression

For the last 20 years or so I have been following the solar cycles.  Each dot represents the previous month’s tally in how many active solar spots occurred during that month.  The count was well above the 25 level, but it’s not finished yet. This solar cycle #24 still has a few years to go as it should roll around the bottom for many months as well.

Spotless Days
Current Stretch: 5 days
2017 total: 61 days (21%)
2016 total: 32 days (9%)
2015 total: 0 days (0%)

2014 total: 1 day (<1%)
2013 total: 0 days (0%)
2012 total: 0 days (0%)
2011 total: 2 days (<1%)
2010 total: 51 days (14%)
2009 total: 260 days (71%)

In the last 5 days no sunspot activity has been recorded, I’m  sure long stretches of inactivity will still get recorded before solar cycle #25 comes along.

Huge solar storms still come in from big holes in the sun, which produce the beautiful auroras to the north. Tourists from around the world regularly visit places in Alaska and Sweden to witness these stunning displays. Many planets in our solar system also display auroras, but with different colors. Storms from the sun can produce massive disruptions on earth and the astronauts in the ISS have to go into the safe room until the threat passes.

Without the protection of our magnetic field our DNA would get resequenced, basically exterminating all life on earth. One of the last solar cycles that was this low happen back in the early 1900s.
