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.
