Hi,sorry this is late,Managed to see Aurora Borealis this March gone.Seen from Flowerscar Road near Todmorden .Could see light green cast about 22 30 which intensified towards Midnight,i couldnt see any purplish colour with naked eye,which camera picked up,but certainly could see the Green ,amazing to see Locally ,all the conditions have to be perfect to have a chance,but it does happen occasionally.Regards Brian.
