Mystery flash streaks across night sky

At 9:46 p.m., Vahalia tweeted:

Did anyone else see the bright flash in the sky over the Seaport area?

And the local Twitterati responded:

Karl Stier:

I saw the light from West Roxbury, east towards the city, very bright and at a downward 25 degree angle.

Jeff Megargell:

I saw it too, more like a 85 degree angle for me and it was a green hue!

Ejm7789:

Saw the same. at the Sox game. what was that? I saw green streak. Thought it was a shooting star it wasn't. Fireworks?

Garrett Quinn:

This is how Cloverfield starts.

Ryan Breton:

Most reports suggest a meteor, sighted NW to SE from ME to Long Island!
