Well put, I was thinking the same thing...stared and flaged though because of the sheer peek-a-boo factor. I feel there may be more to this event
than we're being told, a little digging is in order.
However, there is no significant H (6563 °A) emission
or absorption, which would be expected for the presence
of strong H and H features. (Although there is
slight evidence for emission at 6563 °A in the Keck spectrum,
this is not seen in the VLT or Subaru spectra
The second brightest supernova discovered in modern times, SN 1993J, was found in the beautiful spiral galaxy M81 on 28 March 1993. From archival images of this galaxy taken before the explosion, a red supergiant was identified as the mother star in 1993 - only the second time astronomers have actually seen the progenitor of a supernova explosion (the first was SN 1987A, the supernova that exploded in 1987 in our neighbouring galaxy, the Large Magellanic Cloud). Initially rather ordinary, SN 1993J began to puzzle astronomers as its ejecta seemed too rich in the chemical element helium and instead of fading normally it showed a bizarre sharp increase in brightness. The astronomers realised that a normal red supergiant alone could not have given rise to such a weird supernova. It was suggested that the red supergiant orbited a companion star that had shredded its outer layers just before the explosion.
