Abstract :
[en] IR (1-20 micron) observations, photometry, and narrow band spectrophotometry of SN 1987A obtained between March 16 and October 12, 1987, are presented. Variations of the bolometric luminosity are determined from IR and optical photometry. The spectral energy distribution, effective radius, and effective temperature of the hotter component are derived. Also, observations of hydrogen lines and CO emission are discussed.
