Solar activity today September, 25th

Posted by

In the early morning was announced a very weak geomagnetic storm then evidently retracted. Meanwhile, they are 12 days without sunspots with a very poor 68 sfu radiation for propagation purposes on the HF bands that are affected by the F2 layer of our ionosphere. Well the MUF / f2 this morning has however reached up to 22Mhz around 9 utc then down. So far this year, the sun has been without sunspots for more than 154 days–including the last 12 days straight. To find a similar stretch of blank suns, you have to go back to 2009 when the sun was experiencing the deepest solar minimum in a century. Solar minimum has returned, bringing extra cosmic rays, long-lasting holes in the sun’s atmosphere, and strangely pink auroras.
