This model gives a forecast of the intensity of the auroral oval and is based on the solar wind conditions and the Interplanetary Magnetic Field. The map shows the intensity and the location of the auroral oval for the time given in the bottom of the map. The forecast is based on the current solar wind conditions and the average time for the solar wind to propagate from the ACE satellite at the L1 Lagrange point to Earth. The red line indicates how far away viewers on the ground might see the aurora, assuming good viewing conditions.
These plots shows you the current extent of the auroral oval in the northern hemisphere (left) and the southern hemisphere (right), extrapolated from the measurements taken during the most recent pass of the NOAA POES satellite.
The red arrow points to the direction of the sun (daylight side).

A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!

A Coronal Mass Ejection (CME) has arrived at the ACE satellite. The solar wind speed rose with 81.51 km/sec to 598.3 km/sec.
