Comet Holmes was discovered in 1892 by Edwin Holmes. Similarly to the time of discovery, comet holmes rapidly increased in brightness at 24. October 07 due to an unexpected outburst. The absolut brightness actually increased by about 500'000 times which probably occured because of a break up of the comet or a sudden exposure of ice. Since then, the bright coma is expanding and has reached about 27arcmin in diameter at this stage.
Holmes will continue expanding and continuously fading out during the next weeks. The bright star in the image above is Mirfak (Alpha Persei).
