True, but I was trying to address OP's question about visibility in Boston. The article's claim that the lights could be visible in New England tonight is pretty misleading though, since the max Kp forecasted is 4.67. That has the potential to produce camera-visible auroras low on the horizon in far northern Maine, but certainly nothing visible to the eye.

Unfortunately this this article is full of inaccuracies, the SWPC isn't forecasting activity tonight that's strong enough to be seen anywhere near Boston. Last night, the lights were visible in southern Maine, but the solar storm has diminished significantly from last night. Even then, I had to drive two hours north of the city to get enough dark sky to see anything.

I took a taxi from the airport last Sunday about 11am and I'd probably do that again if I were in your situation. Oddly there were no taxis at the taxi stand but they radioed for one and it showed up in about 3 minutes, which is better than what you can expect from Uber/Lyft even on a good day. Once on the road there was minor traffic in the tunnel but no real delays.

Colortek is the answer. They've been reliably working with film in all kinds of formats for decades.

I did it this morning for a 5am flight and Uber worked fine. I allowed an extra 15 minutes in case it took a while to find a driver but I didn't need it.
