We welcomed back Dr. Pal Brekke to discuss the Northern Lights, his new documentary video on the Northern Lights, and solar activity.  During our one hour show, we started with the Northern Lights and his video, “Northern Lights-a Magic Experience DVD.”  You can see the trailer to the video and order it at www.solarmax.no/Aurora/DVD.html.  Dr. Brekke introduced us to the Northern Lights, talked about Northern Lights tourism, and where the best locations are to see them and during what season.  Our guest was asked about the same thing happening in the southern hemisphere and he said yes, the Southern Lights or Polar Lights.  Not only did Dr. Brekke talk about his documentary video but we discussed some of the mythology associated with the Northern Lights, mostly on the fear side of things.  Dr. Brekke then talked about how the Northern Lights can move south, sometimes even being visible as far south as Florida.  He then explained why this happens re the solar wind putting pressure on Earth’s magnetosphere.  Our guest was asked about the various colors in the lights and he explained it using a neon tube for advertising purposes as an example.  B John asked a series of questions including one about telescopes and gravitational lenses.  We then switched over to talk about sunspots, CMEs and the 11 year solar cycle.  A listener asked Dr. Brekke to explain solar weather and space weather, then Dr. Brekke was asked if Earth’s climate is impacted by sunspots and if so, how.  Don’t miss this discussion.  Jack sent in a question asking how close one can get to the sun without feeling the intense temperatures or having hardware destroyed.  You will be surprised by what Dr. Brekke said in response to this question so don’t miss it.  Our next topic included short comments on existing and future solar missions planned from Europe and the U.S.  B John then asked about a possible repeat of the Carrington Effect and what that might mean for Earth based and orbiting electronic hardware.  Dr. Brekke had much to say about such an event and the potential damage that could happen were another Carrington Effect realized.  Near the end of our discussion, a listener asked our guest how best to take photos of the Northern Lights.  He suggested using an SLR type camera, not a point and shoot or cell phone camera, use a tripod, a low f stop and a very high ISS setting.  He then touted the Sony A7S camera.  Before our discussion ended, our guest was asked about the best tools for solar research over the past decades and most important findings.  Again, don’t miss his answer.  As the show was about to end, the final listener question was how scientists predict how much life is left for our sun. Wait till you hear how much hydrogen the sun burns every second!
