What do the Aurora prediction symbols mean?
Our own prediction symbol shows the possibility for aurora sightings. The values are based on scientific measurements, weather and lighting conditions. E.g if it is dark, a clear sky and good solar activity it will calculate higher possibilities for an aurora sighting. Values are none, low, good or high.
What is the Aurora forecast indicator?
This Aurora forecast indicator (known as “planetary K-index”), is simply a scale to measure the geomagnetic activity that is directly related to Northern Lights visibility. Here you can learn a little more about what causes the northern lights.
Can scientists predict when and where Aurora will occur?
Scientists can predict when and where there will be aurora, but with less confidence than they can predict the regular weather. The ultimate energy source for the aurora is the solar wind. When the solar wind is calm, there tends to be minimal aurora; when the solar wind is strong and perturbed,…
Why can’t I see the aurora borealis in Alaska?
Sunlight prevents viewing the aurora during the summer at high latitudes. The skies at night are simply too bright as the sun climbs in the sky until the June 21 solstice and then descends. Here in Fairbanks, at about latitude 64.8, our aurora viewing “season” is August 21 to April 21.
How far in advance can aurora be predicted?
As a naturally occurring phenomenon, the appearance of the Northern Lights is notoriously difficult to predict any further in advance than about two hours before it happens.
Will 2022 be a good year for aurora borealis?
“There will continue to be aurora viewing opportunities in 2022,” Steenburgh said. “The solar cycle is indeed ramping up and as solar activity increases, so do the chances for Earth-directed blobs of plasma, the coronal mass ejections, which drive the geomagnetic storms and aurora.”
Can auroras be predicted?
The KP index is the most common way to forecast the Northern Lights, and you can use it both for short-term and long-term Aurora prediction. This Aurora forecast indicator (known as “planetary K-index”), is simply a scale to measure the geomagnetic activity that is directly related to Northern Lights visibility.

Unfortunately, a traditional moon calendar only answers question #3, the least important of the 3. The moon can be below the horizon for an entire night of aurora viewing and be as much as 80-90% illuminated and can be up in the sky all night long with 1% illumination. Further down on this page we have provided links for our custom moon calendar that answer these questions from an aurora viewers perspective in more detail.

What is the new version of the OVATION Prime model?
In 2020, NOAA SWPC implemented the new version of the OVATION Prime model into operations. This version has been dubbed OVATION 2020. The Auroral Forecast product is based on the OVATION Prime model developed by P. Newell at the Johns Hopkins, Applied Physics Laboratory.
What is the OVATION model?
The OVATION (Oval Variation, Assessment, Tracking, Intensity, and Online Nowcasting) model is an empirical model of the intensity of the aurora developed at the Johns Hopkins University, Applied Physics Laboratory by Patrick Newell and co-workers1. The model uses the solar wind velocity and interplanetary magnetic field measured at the L1 orbit position at 1.6 million km (1 million miles) upstream from earth as input and calculates three types of electron precipitation and the proton precipitation which strongly correlate with the aurora. An estimate of aurora viewing probability can be derived by assuming a linear relationship to the intensity of the aurora. This relationship was validated by comparison with data from the Ultraviolet imager (UVI) instrument on the NASA Polar satellite (2).
What is the aurora?
The aurora is an indicator of the current geomagnetic storm conditions and provides situational awareness for a number of technologies. The aurora directly impacts HF radio communication and GPS/GNSS satellite navigation. It is closely related to the ground induce currents that impact electric power transition.
How long is the Aurora product forecast?
This is a short-term forecast of the location and intensity of the aurora. This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the aurora. The forecast lead time is the time it takes for the solar wind to travel from the L1 observation point to Earth.
Why do auroras turn red?
The green ovals turn red when the aurora is forecasted to be more intense. The sunlit side of Earth is indicated by the lighter blue of the ocean and the lighter color of the continents. Aurora can often be observed somewhere on Earth from just after sunset or just before sunrise.
What is the forecast lead time?
The forecast lead time is the time it takes for the solar wind to travel from the L1 observation point to Earth. The two maps show the North and South poles of Earth respectively. The brightness and location of the aurora is typically shown as a green oval centered on Earth’s magnetic pole.
Who developed the ovation model?
Machol and Redmon (NCEI) developed the real-time ovation model. Viereck (SWPC) implemented the model and developed the graphical products to run in realtime to create aurora forecasts. In 2013, Newell upgraded the OVATION Prime model so that it would more accurately capture large geomagnetic storms.
