A slow but steady increase is seen in the 10.7cm solar flux since late September. This is the longest sustained upward trend in the electromagnetic emissions since early 2008.
It is yet another indicator that the sun continues to awaken from its pronounced solar sluggishness.
Observe the black line at the top of the graph. There is a gentle, but definite upward slope from left (older data) to right (newest data). This is the 10.7cm flux reading.
This further supports solar researchers’ viewpoint that solar activity is climbing out of the cycle 23/24 minimum, which was the most pronounced since 1913.
