  We present the discovery of the highest velocity CIV broad absorption line to
date in the z=2.47 quasar SDSS J023011.28+005913.6, hereafter J0230. In
comparing the public DR7 and DR9 spectra of J0230, we discovered an emerging
broad absorption trough outflowing at ~60,000 km/s, which we refer to as trough
A. In pursuing follow up observations of trough A, we discovered a second
emergent CIV broad absorption trough outflowing at ~40,000 km/s, namely trough
B. In total, we collected seven spectral epochs of J0230 that demonstrate
emergent and rapidly (~10 days in the rest-frame) varying broad absorption. We
investigate two possible scenarios that could cause these rapid changes: bulk
motion and ionization variability. Given our multi-epoch data, we were able to
rule out some simple models of bulk motion, but have proposed two more
realistic models to explain the variability of both troughs. Trough A is likely
an augmented `crossing disk' scenario with the absorber moving at 10,000 < v
(km/s) < 18,000. Trough B can be explained by a flow-tube feature travelling
across the emitting region at 8,000 < v (km/s) < 56,000. If ionization
variability is the cause for the changes observed, trough A's absorber has n_e
>= 724 cm^-3 and is at r_{equal} >=2.00 kpc, or is at r < 2.00 kpc with no
constraint on the density; trough B's absorber either has n_e >= 1540 cm^-3 and
is at r_{equal} >= 1.37 kpc, or is at r < 1.37 kpc with no constraint on the
density.
