Meteor showers can, and sometimes do, produce massive fireballs. So if a
fireball occurs during a known shower, it isn't surprising to see some
reference to that in news reports. I always check the radiant of fireballs
against known showers to rule out the possibility that the fireball is a
shower member.

That said, fireballs from showers occur quite high and don't produce sonic
booms. Once multiple camera views are integrated to come up with an
atmospheric path for this event, it will be apparent that the meteor is not
connected with a shower.
