You can see any current alerts here, and a forecast here. We also have an easy to understand guide on how to take images of the Aurora here

If the below data doesn't automatically update, please refresh the page


This is a 30-40 minute forecast and shows the probability of OVERHEAD aurora (not probability of seeing on the horizon).

The colours of the Aurora are colour coded based on the probability of seeing the Aurora OVERHEAD at a location (see bottom left of map for key)

This is a guide only. Auroras may or may not be visible, visibility depends on other data such as Bz (see further down this page for explanation on Bz).

This Ovation model is from NOAA SWPC Website

This chart is from NOAA It updates every minute to show the current planetary Kp index.

Look for a red bar as this means the Kp levels are high, the Kp number can be found at the left of the chart.

Yellow means there is a disturbance and green means low activity.

This graph is from the NOAA SWPA Website and shows real time data of the Solar wind.

The graph shows:

Bz - Direction of the interplanetary magnetic field (IMF)

Phi - The angle of the interplanetary magnetic field

Temp - The temperature of the solar wind

Density - Density of the solar wind

Speed - Solar wind speed

A simple explanation and what to look for in the plots:

Bz (Red Line)

The most important things to look for in the graph. The Bz MUST be south for a good display to take place. Moderate and Strong South is a good indicator that the Aurora may be seen from our location.


<0 South

-10 moderate South

-20 Strong South

Density - Dense solar winds can help produce a good Aurora storm. A value above 20p/cm³ helps to contribute to an Aurora storm, but as this isn't as important as Bz and Speed a storm could develop with lower density readings.

<10 low density

20> moderate

40> high density

60> very high density

Speed - for our area a speed of more than 700 km/sec helps. This does depend on the Bz though, if this is moderate - strong South it could cause Aurora without this figure being met.

<400 normal speed

500> moderately high speed

700> very high speed

900> very high speed

This model is produced by the U.S. Air Force Weather Agency and shows the global observed Kp and a forecast Kp for the next 1 and 4 hours. Please consider the the 4 hour forecast is only a forecast and may change. The model updates every fifteen minutes.

Key to reading the model:

Green circles and plus symbols

1-hour predictions are plotted with green filled-in circles

4-hour predictions are plotted in green plus (+) symbols

Green bars

The solid horizontal green bars show the 3-hour interval over which the latest predictions are valid

Vertical error bars are plotted in green to show the 50% confidence interval

Blue Line

The solid blue line is the observed Estimated Kp index

Red Line

The dashed red line indicates the lowest alert level, G1 (minor)
