We update the light curves of SN 1978K from the X-ray, optical, and radio observations that we have obtained over the past 5 years. We also include an ultraviolet spectrum obtained with the Hubble Space Telescope as well as an optical spectrum. The X-ray light curve remains constant within the errors. In the HST spectrum, we detect emission lines from Ly-α, [Ne IV] 2422-2424 { Angstroms}, and the Mg II doublet at 2800 { Angstroms}. The optical light curve is consistent with a constant source, although recent observations suggest a slight increase in brightness. The radio light curves are continuing their decline. We discuss the implications of these observations for our understanding of SN1978K.
