I was surprised to see this over the Northern Bay at Sunset last night. It was very close and probably fell into the Gulf of Maine. It was travel from North to South. I had never seen a meteor before.

Here is a video of some meteors:

However, if you try this on the nights around December 13 you are in for a treat. This is when the Geminids meteor shower peaks. The typical rate at the peak is around 50-80 meteors per hour (this is on top of the 10 per hour background rate), so if you spent even 5 minutes looking up at that night you are practically guaranteed to catch a few.
Not entirely true. While the VAST majority ARE very momentary, there are a couple or three every night which may last upwards of 10 seconds or so, especially if it's large, breaks into several pieces, & is from one of the typically "low streams".
Every single meteor shower has a very distinct personality ... bright & fast, slow with long trails, many pinpoint flashes with no trail, lots of bolides (painfully bright ones), even large percentages of specific colors. And then there are always orphan meteors, from no known stream, which can be almost any type.
And then too, if either you are making long-exposure photos, or if a bright flash didn't ruin your night vision, the tails of a few per night may last for a minute or more ... a ghostly white serpent being slowly warped by upper air currents.
I've been an astronomer for well over 2 decades, have probably averaged 200+ nights each year doing at least an hour or so of observing, and Have seen at least 1 decent meteor every single time. Even if the observing/photo session is over, if I've yet to meet thatreal good one, then I'll ALWAYS stay out until I finally see that one good one, then I call it a night. It rarely takes longer than 30 minutes before that happens.
Two automatically come to mind as belonging to that really good group. One was at a Drive-In Theater (anyone remember those?) and was behind & above the screen. The other was brilliant green & HUGE in size, seen with a friend while floating a river. The first was much longer in both size & time, the latter was much more brighter & colorful. Both lasted about the same amount of time, around 5-7 seconds. That green one could have also been an omen, since we were illegally spotlight raccoons & had already knocked a little hole in the boat on a rough shoal. :( :(
But yeah, there's AT LEAST 2 or 3 SupeEteors every single night if you happen to be looking up at the right time ... or down too, since many of these can make shadows. And these are the type which very often last ridicously long.
-----------------------------------------
Deepwoods, this one most likely never made it to the ground. Atmosphere entry is a VERY brutal affair & believe-it-or-not, most of the ones around this same brightness & size are only about the size of a marble or quarter. There's just not enough mass there to keep it from totally vaporizing.
In order to make ground contact, it'll need to start out about the size of a softball or so, and have a very favorable entry angle. In that case, you MIGHT get a dime-size one on the ground or in the water.
The ones which survive entry as a good size chunk, say a couple/three inches or so, were probably the size of watermelons & would have most likely left a very prominent trail across half of the sky. For a second or so, they would have been the brightest thing in the night sky, maybe competing even with Luna, & could have very easily have been visible in daytime.
I do believe you are the first to capture and post a photo of a large meteor. Lucky shot!
To Avtanski, lolol.....I can't see anything from my yard, as I live deep in the Maine woods and the pine trees block my view. But the Bay is very near my cottage, so I have a great view of the sky from there! Thanks for you information too!!

Thank you, Andras. I'm going to look for the meteor shower tomorrow night! YES! It was like being closer to the creation of the universe!!!
