I just found the greatest thing, smiling from ear to ear all I can think about is sharing Aurora Cam. This link takes you to a site with further links to aurora cams set up around the world. In real time, or in the case of the cam at Yellowknife, NWT which I’m currently glued to – updated every 20 seconds – watch northern lights as they happen around the world. Don’t expect a planetarium laser show every time – just sit back, get comfy and let aurora cast her spell.
Each cam will tell you if geomagnetic action is taking place. To get the most out of this without losing interest – keep an eye on http://spaceweather.com/ the site is updated every 10 minutes and gives advance warning of solar impacts as well as estimated intensity and scope. When spaceweather indicates solar storms in progress – high tail it over to Aurora Cam.
