Solar Cycle 24 continues to ramp up

Posted Thursday November 19, 2009 at http://www.wcflunatall.com/nz4o4.htm

The Cycle 24 sunspot group that I mentioned on November 18, 2009  has been numbered 11033 by the NOAA/SWPC.

It is located near N17E20 and contains a beta magnetic signature capable of producing very small B class solar flares. As mentioned yesterday SIDC Belgium assigned it Catania #28.

The old solar cycle 24 sunspot group #11029 has produced new sunspots and has been re-numbered 11033 by NOAA/SWPC. SIDC Belgium has given the sunspot group Catania 30.

It is located near N21E47 and contains a beta magnetic signature capable of producing very small B class solar flares.

The NOAA/SWPC sunspot number is 29 (the second highest so far for solar cycle 24) and the SIDC Belgium sunspot number is 30. The solar flux index (SFI) is 77.4.

The new sunspot groups could push the SFI above 80 in coming days. This would raise the maximum usable frequency (MUF) of the F layer high enough to improve propagation conditions on 20, 17 and 15 meters.

Solar cycle 24 continues to ramp up this month!
