my northern horizon monitoring camera is showing a green horizon www.davegradwell.com/hamcam.html
Large displays of northern lights have been reported over the US during the morning.
Again stay tuned as this story changes by the hour
These events are notorious to predict and only time will tell what we get. As a guide -
The K value on the top of the graph: values of 5 mean a good display for the north of the country and values of 6 and above mean northern lights for most of Ireland.
The graph: Watch the red graph, displacements of 70nt (1.5 boxes) are needed for displays over most of Ireland.
and of course stay tuned to Surfing the Sun
The impact (called a sudden impulse) is clearly visible on my magnetometer www.davegradwell.com/magnetometer.html
displays of the northern lights are expected over the weekend. a coronal mass ejection (a piece of sun hurled into space) is due to impact earth Saturday evening sparking aurorae. as usual watch my magnetometer page www.davegradwell.com/magnetometer.html to see when it hits. alerts will be given here and on my Facebook page. stay tuned....
