John Batchelor and I welcomed back Dr. Dean Pesnell to discuss Solar Cycle 25 which we have now entered.  Dr. Pesnell was part of the Solar Cycle 24 Prediction Panel so we started off with a short Q&A about the Solar Cycle Prediction Panel. Dr. Pesnell talked about the sun having been studied for around 400 years but now with solar satellites and technology, we are learning much more about it as well sunspots and their cycles.  Some of the additional topics talked about included space mission planning with space weather.  Artemis was a good example of this, plus he talked about planning shielding for CME protection and more.  I asked our guest about sunspots and climate change.  You might be surprised by what he said on this topic.  Dr. Pesnell had much to say about Cycle 25 which we are now in because it does and will impact Earth.  Before our single segment ended, both John and Dr. Pesnell worked in additional topics you will want to hear about.

Please post your comments/questions for this discussion on this blog for this show.
