What's that bright red spot roughly in the triangle between Madison, Milwaukee, Chicago? And another one below Osnabrück, Germany in Georgsmarienhütte? What could cause this? Hardware error? Miscalibration? Hrrm. Closed the tab and reloaded. 'Triangle' (Eagle Springs) back to normal, Georgsmarienhütte still RED, new one in Taipeh RED. Strange. Maybe software error? Or are the naturally occuring fluctuations that fast? Hrrm. Letting it run for a while, refreshing itself. Taipeh back to normal, Georgsmarienhütte still red. Additionally Nebra(Unstrut), Germany red. Don't know what to make of this. Seems 'wonky'?
