Coronal hole gamma detection?

On October 4th this hole opened up in the sun's corona -


At the same time, this happened at my SI-180g station - southofhobart3, which is particularly sensitive to gamma and xray



I suspect a connection.

The two other stations at this location did not register this detection, but they also have different GM tubes.

That detection on the 2nd was a radon washout event. In Tasmania when the conditions are right (or wrong?) we get huge radon washout from, I suspect, the very very large uranium mine in South Australia (S.A.)- Olympic Dam.

The current detections stand alone in that the airflow is from the Southern Ocean rather than S.A. - and there is currently no rain or weather front near Tasmania.
Plus the coinciding coronal hole.
The station southofhobart2 also has a UV sensor which can be viewed at thingspeak.com, so I will be watching that data closely.

readings normalised overnight and elevated readings resumed after sunrise.
Nothing unusual noted on any other geiger counter.
Hmmm...
