On board an airplane departing the Charlotte area, Haruko conveyed that there were tornado warnings in the area on this day. From what it appears, the cloud column that is reaching the ground shows signs that it might have been a brief tornado touchdown near Charlotte, North Carolina, US.

Alan, I’ve just come across an interesting video (2.45 minutes duration) taken from NASA’s Astronomy Picture Of the Day (APOD) website showing a very rare combination of Noctilucent clouds accompanied by Aurorae on the night of 4th & 5th August recent at Caithness, Scotland:-

Certainly worth watching! The text is informative too.

Excellent shot, Alan.
