Spectroscopic and photometric observations of SN 1987A- V. Days 386-616.

We present spectroscopic and UBV(RI)_c_JHKLM photometric observations of SN 19S7A in the Large Magellanic Cloud made at the Sutherland observatory of the SAAO between days 386 and 616 after the Kamiokande-II neutrino event. During this period the bolometric flux from the supernova measured over the U to M wavelength range has continued to decline faster than the ^56^Co decay rate. By day 56O the flux in this wavelength range accounts for only half of that expected from ^56^Co decay. The estimated total flux (including X-ray and γ-ray data) is consistent with ^56^Co remaining the sole energy source of the supernova over the period considered.
