Posted Sunday November 15, 2009 at http://www.wcflunatall.com/nz4o4.htm Yesterday yet another solar cycle 24 sunspot group emerged, this time in the NE quadrant of the Sun near N29E35. As of yet it has not received a number by SIDC Belgium or NOAA/SWPC. If numbered by NOAA/SWPC it would receive #11031.
This new sunspot group pushed the solar flux index (SFI) to 75.9 yesterday and 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. Under the very old method of counting sunspots SIDC Belgium gave the sunspot group a number of 11. But in reality only one simple sunspot actually emerged. The solar cycle 24 sunspot group that emerged on Friday November 13, 2009 that received SIDC Belgium Catania #25 and located in the SW quadrant of the Sun has faded, with it's remnant Plage currently setting around the west limb of the Sun. It did not receive #11031 by NOAA/SWPC. Also yesterday old solar cycle 24 sunspot group #11029 rose above the east limb of the Sun but is only a large Plage with no sunspots. Last month #11029 made it's debut as the largest and most active sunspot group in fledgling solar cycle 24. 73 & GUD DX, Thomas F.
