SN Searching - Part 2.


  • Monitor the target galaxies, at various windows of opportunity, at least twice per month.
  • Become familiar with the Galactic star field, so instant recognition of any intruder star would become apparent.
  • In programs involving CCD imaging devices....take "base images" to compare with later monitorings of a particular galaxy.
  • After careful scrutiny of a new suspect (checking for asteroids, variable stars, HII regions, etc.) request confirmation of the suspect from the International Supernovae Network and follow the ISN guidelines to determine if your suspect is a bonafide supernova.
Although no figures are available on the negative observations that occured in this area during the past two years (to indicate a SNe "hit rate"), I would have to infer that the rate would be considerably improved if more discipled visual/CCD searching in this area were undertaken.

Good luck and good Hunting.....
