I am still concentrating on trying to obtain the best R data in order to identify any polar activity (I found that the polar storm of last year was best seen in R in my captures). This image is a composite of 4 derotated images captured over a period of 6 minutes. The polar hexagon and polar vortex are just about detected. [Clyde Foster:Centurion,South Africa]
