Although solar activity is quite low, we did see an increase in sunspot numbers and solar flux over the past week. Average daily sunspot numbers were up nearly 20 points, or about 36 percent, to 74.1. Average daily solar flux increased nearly 13 points to 108.7. There was also quite a remarkable increase on Thursday, August 30, when the sunspot number jumped 23 points from Wednesday's value to 118, and solar flux was up nearly 10 points in one day to 127.8...

Chance of M-class Flares

On September 1 SpaceWeather.com reported a 40% chance of M-class flares in the following 48 hours

They say: Sunspot AR1560 has more than quadrupled in size since August 30, and now the fast growing active region is directly facing our planet: movie. NOAA forecasters estimate a 40% chance of M-class solar fares during the next 48 hours.

SpaceWeather.com also report on a a coronal mass ejection (CME) that occurred on August 31 see

CME Impact on Sept. 3rd

As expected, a coronal mass ejection (CME) hit Earth's magnetic field on Sept. 3rd at approximately 1200 UT (5 am PDT).
The impact induced measurable ground currents in the soil of northern Scandinavia and sparked bright auroras around the Arctic Circle.
At the time this alert is being issued, a moderately strong (Kp=6) geomagnetic storm is underway.

Propagation de K7RA

6 October, 2012
ARLP040

A coronal mass ejection (CME) hit Earth on September 30, triggering a jump in geomagnetic indices. The planetary A index on October 1 was 31, and the K index went as high as 7, making aurora visible across the northern tier of the United States. Strange, but the northern latitude college A index was 23 (near Fairbanks, Alaska), about the same as the mid-latitude index, which was 21, in Fredericksburg, Virginia. During a geomagnetic disturbance it is common to see indices go much higher in the far-northern latitudes.
Average daily sunspot numbers declined 8.3 points to 73, and average daily solar flux was off exactly one point, to 128.7..... http://www.southgatearc.org/propagation/2012/k7ra/040_october_06.htm

Sunspot activity rose this week, with average daily sunspot numbers up over 45 points to 97, and average daily solar flux rising over 24 points to 129.2. October 12-14 had high geomagnetic activity, with a planetary A index at 12, 38 and 19, college A index (in Alaska) at 18, 70 and 33, and mid-latitude A index (measured in Virginia) at 12, 28 and 20. On October 13 solar wind spilled through a gap in our Earth's magnetosphere, unsettling conditions here. Aurora was seen across the northern tier states in the United States.....
