Stellar-mass black holes in the Hyades star cluster?

The Hyades star cluster is 153 light years away[0]. A supernova 30 - 1000 light years distant is expected to have an effect on the Earth's biosphere[1]. If one of the black holes goes active, and if the jet is pointed at us, what might be the effect?

For stellar mass black holes, I don't think jets would have a significant effect this far away. The jets that travel really long distances are associated with supermassive black holes (billions of solar masses) powering quasars.

Null! The BH is way too small. We're talking about jet when dealing with SMBHs.

That's "super massive", not "stellar mass", right?
