The sun is currently blank with no visible sunspots and this is the 14th straight day with a blank look which is the longest such stretch since April 2010 according to spaceweather.com. Historically weak solar cycle 24 continues to transition away from its solar maximum phase and towards the next solar minimum. In April 2010 – the last time there was a two week stretch with no visible sunspots –  the sun was emerging from the last solar minimum which was historically long and deep.  There have already been 26 spotless days in 2017 (34% of the entire year) and this follows 32 spotless days last year which occurred primarily during the latter part of the year. The blank look to the sun will increase in frequency over the next couple of years leading up to the next solar minimum – probably to be reached in late 2019 or 2020.  By one measure, the current solar cycle is the third weakest since record keeping began in 1755 and it continues a weakening trend since solar cycle 21 peaked in 1980.
