Can I see the Northern Lights tonight?

Aurora visibility depends on the Kp index and your geomagnetic latitude. At Kp 3, aurora is typically visible only near the Arctic and Antarctic circles. At Kp 5 (a G1 storm), the auroral oval expands south into the northern U.S. and northern Europe. At Kp 7+ it can reach mid-latitudes. The report above compares your latitude to the current auroral boundary in real time.
