For a shift from about 700nm to 350nm: coming right at you at 0.6c

It would also have a kinetic energy of about 1.1234 Petajoules, on the order of magnitude of the Tsar Bomba

Kinetic energy or total energy? Assuming the rose weight 10 grams I get that 1.12PJ total energy, but only 0.23PJ is kinetic.

In hindsight I was a bit generous with the weight, I assumed 50g

Only 10MT instead of 50 then?

One ton of TNT is 1E9 calories which is 4 gigajoules. So 0.2 petajoules should be only 50 kilotons of TNT?

A fart in the wind next to the Tsar Bomba. My disappointment is immeasurable and my day is ruined.
