Vermont is located beyond the so-called aurora oval around magnetic poles. However, if geomagnetic activity is high enough, Vermont residents and guests have a solid chance to see the beautiful spectacle which colors the skies in green, purple, and red. The northern lights could be seen quite well in the North Country and Upper Valley regions.
The season of northern lights chase starts in the fall. The times of autumn and spring equinoxes usually coincide with increased geomagnetic activity, hence your chances to see northern lights in Vermont grow. Winter is also a good time to chase aurora due to darker and longer nights. By April you chance to see aurora decrease considerably. Don't forget to check KP-index of geomagnetic activity. If it's higher than 5, you can pack your photo gear and try your luck in chasing elusive aurora.
