Willowbank Observatory – Simple Auroral Magnetometer
Above you will see todays graph of the readings from the Magnemometer. The higher the values, the more likey the Aurora Borealis is visible from Arran too. The green line at the bottom of the graph indicates normal geomagnetic activity. If this lines shows yellow, then the geomagnetic acitivity is said to be moderate and possibly visible lower down on the horizon to the north. If the Line is Red, then it is indeed on! If its night time, it’s dark, and there are no clouds to the north, the Auroa will 99% sure to be visible. It does come and go sometimes when its active so wait a few minutes and you should be able to see it erupt into full glow with beams of light rising high into the atmosphere.
Here’s yesterday’s magnemometer graph, handy to find out what the stats were if you saw the Aurora

NOAA’s Ovation Auroral Forecast
Clicking the image above will take you to the full sized version on the NOAA Helios page with full details about how it works and what it means, well worth keeping an eye on. The image looks a bit fuzzy because I have to shrink it to fit the column. The aurora forecast image here is refreshed whenever they produce a new one, usually every 10 to 15 minutes. Aurora hunting in Scotland can be challenging, but also so very rewarding when you witness the Northern Lights in your own area. It is really something quite special.
