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!
