Northern Lights Now – SWPC has posted a G1 geomagnetic storm watch for September 20th and 21st. The high speed wind stream from a coronal hole pointed toward Earth on Sept 17th should arrive just before midnight GMT late on Monday. For viewers in Europe and the East Coast of North America, this means there is a chance for Aurora in the hours just after sunset. Here’s an image of the coronal hole as of the 17th:
