The Kp index is a global geomagnetic storm index with a scale of 0 to 9. Based on the Kp index, you can immediately know if there is a chance to see the Aurora or not. On the world map below, the average equatorward boundary of the midnight aurora is shown based on the current predicted Kp index. This gives us a good indication where we could see the Aurora at the current time for viewers where the local time is in the hours around midnight. The higher the Kp climbs, the closer the lines move towards the equator.
Keep in mind that this is not a precise boundary and that the aurora can still be viewed when it is positioned 4-5 degrees in latitude away from the viewer although it will appear about 20º above the horizon.
Anyone wants to see if there are chances for an auroral display so our site gets lots of traffic. But with higher traffic comes higher server costs. Support our project so we can keep the website online!

Weak CME impact Currently we see the effects of the arrival of a Coronal Mass Ejection (CME) at the ACE satellite. The solar wind speed rose with 107.28 km/sec to 558.2 km/sec.
