Vela is the brightest pulsar (at radio frequencies) in the sky and spins 11 times per second (i.e. a period of 89.33 milliseconds—the shortest known at the time of its discovery) and the remnant from the supernova explosion is estimated to be travelling outwards at 1,200 km/s (750 mi/s). It

Statistically, nearly the 1% of the long-term spin-down of the pulsar is reversed in spin-up glitches, a fraction that is also observed in other monitored pulsars. Careful estimation of the glitch activity and its uncertainty requires statistical tools beyond the simple linear regression.
