Picking a cell phone company and smartphone plan can get complicated fast. How much data you need, what type of phone you want, how important network quality is to you, and how much you’re willing to spend all shape the decision. Continue reading
Since moving to Wisconsin several years ago, I’ve been on a mission to try to see the Northern Lights. I’ve had some success — last fall, I finally saw it and snapped some pictures — but more often than not, either clouds obscure the view, the show doesn’t make it this far south, or I’m too early/late getting out to see it. Space weather seems even more fickle than the clouds and rain we usually think of as ‘weather.’
Along the way on my quest to see the Northern Lights, I’ve found some great online resources:
- NOAA’s Space Weather Prediction Center
- SWPC’s front page provides a good quick look at current conditions, including the current storm level. During the geomagnetic storms that give us the Northern Lights, SWPC staff often post updates at the top of the page.
OVATION Auroral Forecast – SWPC’s OVATION forecast is more of a ‘nowcast’ — the map shows you where the aurora is now. The map’s ‘view line’ shows where the aurora may be visible, but can be a little conservative. There have been times where the ‘view line’ is in southern Ontario, but pictures pour in from the midwest. So, even if you are south of the line, the aurora may still be visible — go take a look!
- NOAA Space Weather scales — So, NOAA says there’s currently a G3 level geomagnetic storm in progress, with the possibility of a G3 level storm tonight. But what’s a G2 or G3 level storm mean? NOAA’s Space Weather Scales lay it out, with examples of how far south the aurora may be visible. For example, in a G2 level storm, aurora may be visible as far south as New York & Idaho (and Wisconsin!). With a G3 storm, it’s visible even further south.
- SWPC Product Subscription Service — You can sign up to receive email alerts of geomagnetic storms from SWPC. There are many different alert types that you can ‘subscribe’ to, but some particularly useful ones are the WATCH and WARNING alerts for G2 or greater geomagnetic storms. The SWPC email alerts have given me a heads-up of geomagnetic storming and allowed me to see (and photograph) the northern lights.
- SpaceWeather.com — This is a great place to go for space weather news. The site also features a photo gallery full of the latest beautiful aurora pictures from users around the world. SpaceWeather.com also offers an alert service that you can subscribe to (for a fee) to receive aurora alerts.
- Twitter is another great resource for aurora news. Some of my favorite Twitter feeds for Aurora news:
Good luck on your own aurora quest!
