Supernova 1993J in M81

The supernova is the brighter star in the lower right.

This image was obtained in spring of 1993 at the Pine Mountain Observatory

using a Lynxx PC CCD camera at the prime focus of the 32-inch telescope.

From Greg Bothun’s Messier

collection.

  collection

  This supernova occurred on Sunday, March 28, 1993, and was discovered by the

  Spanish amateur astronomer Francisco Garcia Diaz from Lugo (Spain).

  He discovered the supernova visually with his 10-inch Newtonian telescope

  at a magnification of 111, as an 11th magnitude star; it later reached a

  maximum brightness of about mag 10.5, around March 31, 1993.

• Radio images of the supernova remnant up to

  18 months after the appearance, taken by the VLBI of the NRAO at 3.6 to

  6.3 cm wavelength.
