Solar Cycle 24 October Update


The 30 day smoothed International Sunspot number for October 2013 was 78.9.  The Sun was more active as indicated by Sunspots and F10.7cm radio flux in October than any time since the middle of July this year.  The chart, by Solen, below shows this activity. (Click on chart to enlarge.)

The chart shows that the NOAA Sunspot number and the F10.7 cm flux are trending downward at month-end, indicating the likelihood that the 30-day smoothed Sunspot number will begin dropping.  A bit of prospective is that while the October solar activity was up, Cycle 24 is still much having much lower activity relative to the 3 preceding Solar Cycles.
