The Tsar Bomba test produced 5.3 yottawatts (about 1% of the power output of the sun) but only lasted 39 nanoseconds.

I wonder if that would be noticeable over interstellar distances?

1% of the Sun's output power seems really huge. Is this accurate? Any references?

According to this:

Tsar Bomba - 5.3 YW

Sun - 386 YW

39 nanoseconds isn't very long (~39 light-feet).

~12 light-meters for our non-metrically challenge friends.

I was using feet to emphasise I was being silly ;-)
