Since I first started doing this photography thang, the toolset for chasing the Northern Lights has evolved significantly.\u00a0 Here are the resources I use now:<\/p>\n<p>First, I subscribe to free email alerts from <a href=\"https:\/\/pss.swpc.noaa.gov\/ProductSubscriptionService\" target=\"_blank\" rel=\"noopener\">NOAA&#8217;s Space Weather Prediction Center (SWPC)<\/a>.\u00a0 Sign up for a free account <a href=\"https:\/\/pss.swpc.noaa.gov\/ProductSubscriptionService\" target=\"_blank\" rel=\"noopener\">here<\/a> and then use the Subscribe link to add the items for which you want to be emailed.\u00a0\u00a0 I use the Geomagnetic Storm Products to determine when the atmosphere is &#8211; or will be &#8211; likely to produce auroras.\u00a0 I subscribe to pretty much every alert in that list of available products, aside from the Kp=4.\u00a0 I use Kp=5 to let me know things are starting to cook, but I won&#8217;t even head out if we don&#8217;t have at least a Kp value of 6.\u00a0 That&#8217;s not the only number to watch, however.<\/p>\n<p>The one-stop-shop you can use for aurora prediction is <a href=\"https:\/\/www.spaceweatherlive.com\/\" target=\"_blank\" rel=\"noopener\">Space Weather Live<\/a>.\u00a0 This really is the gold standard.\u00a0 They&#8217;ve got all the data you need.\u00a0 <a href=\"https:\/\/apps.apple.com\/be\/app\/spaceweatherlive\/id1435501021\" target=\"_blank\" rel=\"noopener\">Even better, they also have an app<\/a>.\u00a0 (Android lusers, you can get it <a href=\"https:\/\/play.google.com\/store\/apps\/details?id=com.spaceweatherlive.app&amp;pcampaignid=MKT-Other-global-all-co-prtnr-py-PartBadge-Mar2515-1\" target=\"_blank\" rel=\"noopener\">here<\/a>.)\u00a0<\/p>\n<p>Remember how I said the Kp is not the only value to watch?\u00a0 It is actually a number which looks back in time over the past three hours.\u00a0 It&#8217;s okay for prediction, but it&#8217;s not much of a real-time value.\u00a0 I combine the current Kp value with the value of the Bz from Space Weather Live to determine if we&#8217;re likely to see auroras.\u00a0 If the Interplanetary Magnetic Field (Bz) is oriented <strong>south<\/strong> we are more likely to see the lights, and the further it deviates from zero the better.\u00a0 This is perhaps the single most important metric I&#8217;ve found to date.\u00a0 I&#8217;ve gone out multiple times when we have a high Kp value, and seen <span style=\"text-decoration: underline;\">nothing<\/span>.\u00a0 But when the Bz is oriented south, I&#8217;ve seen lights on nights when it was otherwise improbable.<\/p>\n<p>Another really cool site &#8211; not so much a tool is <a href=\"https:\/\/www.spaceweather.com\/\" target=\"_blank\" rel=\"noopener\">Space Weather dot com<\/a>.
