Northern Lights Now – SWPC has posted a G1 geomagnetic storm watch for Monday and Tuesday August 29 and 30. KP values are expected to be 5 and higher. Aurora hunters should prepare for a show.
The timing of the storm coincides with a nearly new moon which will make for terrific dark skies. In the northern hemisphere, nights are starting to get longer so there is even more opportunity to have a chance to see the lights.
You can see the current predicted timing of the storm on the NLN AuroraCast page
This storm is due to the return the coronal hole that produced the aurora on august 2nd and 3rd. During that storm, KP values reached as high as 5.67 for several 15 minute periods and aurora pictures streamed in from around the world. You can see that the CH is a little smaller than last rotation, but it is also a little further south. Here is a view of the coronal hole from the last pass and from the current pass.
