Abstract (from CDS):
We present the discovery of several new regions of interaction between the ejecta and equatorial circumstellar ring of SN 1987A, an interaction leading to a much-expanded development of the supernova remnant. We also trace the development of the first such ``hot spot'', discovered in 1997, back to 1995. Later hot spots seem to have emerged by early 1999. We discuss mechanisms for the long delay between the first and later spots.
