  1. Ah, I see -- that makes sense to me now. Thank you so much!
  2. Hi! Question please about the Real-Time Solar Wind charts: Each of the charts has within them a vertical line labeled "Earth." What is the significance of that vertical line? Thanks!
  3. Thank you so much for taking time to explain all of this to me! I appreciate your sharing your expertise!
  4. Thank you so much for the quick reply! We will be near Churchill August 5-11. I'm sorry to say I'm still kind of confused. The key shows that some of the brighter green colors indicate 50% probability of visible auroras, but the hemispheric power chart says below 20GW indicates little of no probability of a visible aurora. So, for example, at 5:45pm UTC (right about now), the hemispheric power charts shows 12GW, which would indicate little or no probability of a visible aurora, but the map shows some fairly bright green in some parts of the auroral oval. Can you help me understand how those two measures square? By the way, if you have time for a specific question, I would be curious to know whether you think we are likely to see any aurora near Churchill August 5-11. Would auroras be common there even in this time of solar minimum? In your judgment, what sort of indicators on the geographical map and/or on the hemispheric power chart would we need to see in order to make it worthwhile for us to wake up to watch for auroras during the short times of darkness that week? Thank you very much for your help!
  5. Hi! I'm hoping you might be able to help me understand better the differences between the auroral forecast and hemispheric power. Currently, the auroral forecast map is showing the probability of visible aurora for the northern auroral oval area at perhaps 10-50% depending upon which area of the oval one looks at. But the Hemispheric Power chart is showing globally integrated total energy less than 20GW, which indicates there may be little or no aurora observable. The two measures don't seem consistent. Can you help me understand the difference? And perhaps also how to best use the information on your website to determine in real time the possibility of seeing an aurora in a certain location (in this case, the location I'm interested in is north of Churchill, Manitoba, at about 59 degrees latitude). Thank you!
