Aurora can often be observed somewhere on Earth from just after sunset or just before sunrise. The sunlit side of Earth is indicated by the lighter blue of the ocean and the lighter color of the continents. The green ovals turn red when the aurora is forecasted to be more intense. The brightness and location of the aurora is typically shown as a green oval centered on Earth’s magnetic pole. The two maps show the North and South poles of Earth respectively. The forecast lead time is the time it takes for the solar wind to travel from the L1 observation point to Earth. This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the aurora. This is a short-term forecast of the location and intensity of the aurora.
