Thick smoke over Brooklyn?

I am down in the south slope area, but looking up north towards downtown Brooklyn, I am seeing a long horizontal cloud of black smoke in the sky...anyone know what's going on? Fire?

I'm in Clinton Hill, and it's pretty close to me. Looks like Gates or Greene & Franklin?

There was thick smoke for a while and now it's dissipated considerably. Lots of helicopters though. Can't find anything on the news yet.

Looks like a big fire?

Looks like this could have been the culprit:

Does anyone know much about this house? Its pretty interesting looking.

Thanks for the info!
