We present data from different epochs in 1978, 1987-1991 and 1996 from theblack-hole candidate 4U1630-47. For the first time we present almost completecoverage of the outbursts which started in 1987, 1988 and 1996. We find thatthe outburst behaviour of 4U1630-47 is more complex than previously realized.The source shows outbursts with durations on the order of ~100-200 days andsometimes intervals of long-term X-ray activity.  The relatively short outbursts which occurred in 1987 and 1996 exhibiteddifferent colour behaviour: the outburst in 1987 showed softening of the X-rayspectrum, whereas the outburst in 1996 showed hardening of the X-ray spectrum,as the outbursts proceeded.  The outburst which started in 1977 may have lasted for up to ~10 months,whereas the outburst which started in 1988 showed activity for up to ~2.4years. Such long-term activity is reminiscent of that seen in GRS1716-249 andin the galactic superluminal sources GRS1915+105 and GROJ1655-40.  We refine the outburst ephemeris of 4U\1630-47 and find that the outburstrecurrence time scale may have changed from ~600 days to ~690 days between the1984 and 1987 outbursts. If the recurrence interval of ~690 days continues, thenext outburst of 4U1630-47 is predicted to occur in 1998 January.Comment: 30 pages including 9 figures accepted for publication in MNRA
