This one is very interesting.

As a Blazar is a supermassive black hole pointing directly toward us it should show the exact effects as the gamma ray bursters but differ in the fact that the black hole is much more massive and the feeding rate is generally rather lower.

Most times in Blazars the accretion disc powers the jet and is seen pole on with the result being a bright starlike point and a blueshifted radiation jet heading toward us at high velocity.

This situation however indicates that the supermassive black hole has got the "munchies" and is busy absorbing a tidally disrupted star resulting in an effect similar to the closing stages of a gamma ray burst where the black hole has already formed and the star has collapsed into and accretion disc surrounded by an outer magnetically affected drag & spin disc. The flare as the tidally disrupted star gets "munched" would resemble the closing stages of a very long duration gamma ray burst.

The interesting bit bit is the diameter of the jet. In this case it would be the diameter of the solar system rather than the diameter of Jupiter which will make it a mite easier to see and a mite more spread out so not quite as bright overall.

Have a nice day: Ag
