Friday we hit a low of 65 this is the same as last cycle low on 21 July 1996.Over the last few days the sun spot count was 0 0 0 0 0 0 0..now we have 68 es increasing each day..We are now entering a NEW CYCLE?
The next HI should be around 2011..but by years end we should see 100 es condx improving on the higher bands

Solar Flux to Bottom Out in July as Cycle 24 Gets Closer: The National
Oceanic and Atmospheric Administration's (NOAA) Space Environment Center
(SEC) released their monthly forecasts of sunspot number and 10.7 cm
radio flux, including high and low bounds to their forecasts. The SEC
forecasts that the smoothed sunspot number reached its low value of 11.7
in March 2007, and predicts that the solar flux will reach its low of
75.4 this month. This is the fourth month in a row that the SEC predicts
the solar flux will bottom out in July. Based on the SEC predictions,
this is probably at the bottom of Cycle 23 and extremely close to the
beginning of Cycle 24. Two events will mark the beginning of the next
sunspot cycle: The observation of the first opposite magnetic polarity
sunspots compared to Cycle 23 sunspot polarity, and the observation high
solar latitude sunspots -- the Cycle 23 sunspots are now very near the
solar equator. The SEC predictions table
and sunspot number
and solar flux prediction graphs
are available on the SEC's Web site.

The geomagnetic field was mostly quiet at all latitudes during the period. Field activity increased to unsettled to active levels beginning late on 03 July through late on 04 July. During this same time interval, high latitudes observed an isolated major storm period midday on 04 July. This activity was due to a solar sector boundary (SSB) crossing (away {+} to toward {-}). The boundary change occurred in a fairly rapid fashion on 03 July beginning at about 1000 UTC. A increase in solar wind density was associated with the boundary crossing with a peak of 12 p/cc detected at 03/2006 UTC. A period of increased interplanetary magnetic field (IMF) variability was also associated with the boundary crossing with total IMF intensity peak of 9 nT at 03/1132 UTC and a minimum southward Bz reading of -10 nT at 03/2103 UTC. Wind velocities increased after the SSB, and peaked at 652 km/s at 04/0931 UTC.

well we have now hit the bottom of the SunSpot cycle with the change of polarity and a low of 65 ..Welcome to the new cycle #24.We can only look for better condition's over the next 2 to 3 year's, gud DX'n soon

The geomagnetic field was quiet throughout the period. However, ACE solar wind data indicated an away (+) to toward (-) solar sector boundary change early on 11 October

The solar flux currently sits at 68 and the sun remains blank. During the last solar cycle minimum in 1996 there was 37 days straight where the sunspot number was 0. Will that record be broken? Time will tell.

The numbers are in for October. This was obviously the lowest month of activity yet. The average Solar Flux for the month was 65.5 which is down for 67.1. The average Sunspot Number was a lonesome 1.3 which is down from 4.8 in September. Besides a few periods of Geomagnetic activity due to the Solar Wind, nothing exciting took place. November is off to a quiet start. Perhaps it is about time things improve.

Days without a sunspot - 26
