There is a slight chance of aurorae reaching as far south as Connecticut and a better chance they could be seen in northern and central New England. Sunspot AR 1618, near top center of the sun in this photo taken Thanksgiving morning, has been producing several M-class flares, including one that will give earth a glancing blow. A geomagnetic storm of level kp 6 is expected to occur in the next couple of days. Such a storm is capable of producing northern lights as far south as Massachusetts and possibly Connecticut. Such storms can also produce minor disruptions in power grids, communications satellites and radio communications.
This map from Accuweather Astronomy illustrates the relationship between kp values and visibility of northern lights in North America:
