10-15-2009 Pole Coronal Hole

This day of observation is the effects on the magnetosphere of a recurrent extension of the northern polar coronal hole . On October 11 it rotated across the central meridian , It was thought by many of the forecasters to be to far North to have anyterrestrial effects. It was not a very intense event and we only reached sub storm levels of geomagnetic activity.

The Solar Winds on this day ranged between 280 & 420 km/s reaching somewhat normal speeds as the the low speed coronal stream arrived
Solar Flux has fluctuated higher over the course of the last few days and our average is back to 70 and for the month the running average remains above 70 but should decline as we move into the second half of October 2009. The planetary A index was 4 and background x-ray flux is below A1

Of course the Sun was blank and it looks like we are going to come in well under the official monthly prediction of 6.8 . We are now at 14 days without a sunspot and have completed 226 spotless days . In only 43 days we will take out 2008 and become the 2nd blankest year in a century . This minimum has already lasted 737 days. By years end we will officially pass from a century class solar minimum to a multi-century minimum that you would have to go back 230 years to find a blanker minimum .

look sideway at it and it looks like a human being in a cloak

cool
