It is a well known fact that for a yet to be fully understood reason, there is an increase in auroral visibility around the equinoxes. That is the only seasonal effect on the occurrence of the aurora. Their visibility though does depend on the amount of daylight and of course the weather.
Both the equinoxes have about 12 hours of darkness, and with the autumnal equinox on average being warmer than the vernal, that's when I would go, IF the weather showed a good chance of being clear. I checked and it looks as though Sept has about 18% chance of being clear and MARCH, 25% , so not a lot in it. This is where I was looking, https://weatherspark.com/y/273/Average-Weather-in-Fairbanks-Alaska-United-States-Year-Round
Incidentally, not all of Alaska is great for aurora viewing, eg Kodiak is about as good as Bismark! Flip between the North American and Alaska views to see what I mean on this site !https://weatherspark.com/y/273/Average-Weather-in-Fairbanks-Alaska-United-States-Year-Round
