31 DAYS OF 100+ SUNSPOT NUMBER: Solar Cycle 25 just hit another milestone. Every day last month (31 days in a row), the sunspot numberexceeded 100. Astronomer Senol Sanli of Bursa, Turkey, used data from NASA's Solar Dynamics Observatory to display all of May's sunspots in a single image:


The last time this happened was in March 2014 when the sun also reeled off 31 consecutive days of 100+ sunspot number. That was near the maximum of Solar Cycle 24.
