  We report on the evolution of the timing of 4U1630-47 during its 1998
outburst using data obtained with the Rossi X-ray Timing Explorer (RXTE). The
count rate and position in hardness-intensity, color-color diagrams and simple
spectral fits are used to track the concurrent spectral changes. The source
showed seven distinct types of timing behavior, most of which show differences
with the canonical black hole spectral/timing states. In marked contrast to
previous outbursts, we find quasi-periodic oscillation (QPO) signals during
nearly all stages of the outburst with frequencies between 0.06Hz and 14Hz and
a remarkable variety of other characteristics. In particular we find large (up
to 23% rms) amplitude QPO on the early rise. Later, slow 0.1Hz semi- regular
short (~ 5 sec), 9 to 16% deep dips dominate the light curve. At this time
there are two QPOs, one stable near 13.5Hz and the other whose frequency drops
from 6--8Hz to ~4.5 Hz during the dips. BeppoSAX observations during the very
late declining phase show 4U1630-47 in a low state.
