North West Cumbria.  Clear skies are like hen’s teeth around here and once again have coincided with near full moon 🙁

I did not notice any aurora visually, though there was a photo on the local weather showing it low in the north.  The spectrograph is very sensitive to this line though which is always present at  a background level even when there is no aurora.
