Scientific paper

The authors present infrared observations of the Type Ia supernova 1984A. This supernova exhibited extremely high velocity material and a fast optical light curve. Despite the very unusual optical properties of SN 1984A, the infrared light curves and color changes of the supernova were similar to previously observed "normal" type Ia's. The J light curve of SN 1984A decayed unusually fast, but the H and K light curves were essentially unmodified. The authors conclude from SN 1984A that Type Ia supernovae may be used as reliable standard candles if they have normal H-K color evolution.
