  We present updated measurements of the Crab pulsar glitch of 2019 July 23
using a dataset of pulse arrival times spanning $\sim$5 months. On MJD 58687,
the pulsar underwent its seventh largest glitch observed to date, characterised
by an instantaneous spin-up of $\sim$1 $\mu$Hz. Following the glitch the
pulsar's rotation frequency relaxed exponentially towards pre-glitch values
over a timescale of approximately one week, resulting in a permanent frequency
increment of $\sim$0.5 $\mu$Hz. Due to our semi-continuous monitoring of the
Crab pulsar, we were able to partially resolve a fraction of the total spin-up.
This delayed spin-up occurred exponentially over a timescale of $\sim$18 hours.
This is the sixth Crab pulsar glitch for which part of the initial rise was
resolved in time and this phenomenon has not been observed in any other
glitching pulsars, offering a unique opportunity to study the microphysical
processes governing interactions between the neutron star interior and the
crust.
