No sunspots on July 17, 2014

For the first time since August 14, 2011, the Sun showed no sunspots on its surface today. It started the day, July 17, 2014, with one small sunspot, but that spot apparently decayed away by the end of the day, as indicated by the fact that the sunspot number for the day was listed as zero, the first time that has happened since the solar maximum ramp up began in 2011.

This is strong evidence that the ramp down to solar minimum is beginning.

    I find it fascinating the sunspot activity is zero. Another recent article I read stated there was something like 17+ years of no observed global warming – I believe satellite data. Correlation? Possibly.

    Thank you Robert

    One nice thing if we are entering a period of Solar quite it would make traveling between the planets much easier. Since Radiation is still one of the top issue with any trip between the planets
