Comet Holmes fizzles out

I checked a couple times during the week, and found that Comet Holmes has been dissipating so much that it is no longer visible at all to the naked eye. With binoculars, it looks like a vague, hazy cloud in the middle of the constellation Perseus, but you would probably never notice it if you weren't looking for it. According to, "the comparatively tiny Comet Holmes has released so much gas and dust that its extended atmosphere, or coma, is larger than the diameter of the sun". Well, it was fun while it lasted. Jacqueline and I saw Comet Hale Bopp once or twice in 1997, and it had a tail that was clearly visible to the naked eye. Some photos can be seen at ASSOCIAZIONE ASTRONOMICA CORTINA.

blog highlights

NOTE: Thus far, only blog posts related to politics and baseball are included in this list.

Blog highlights have been compiled for the years 2010-2012 thus far, and eventually will be compiled for earlier years, back to 2002.


The "home made" blog organization system that I created was instituted on November 1, 2004, followed by several functional enhancements in subsequent years. I make no more than one blog post per day on any one category, so some posts may cover multiple news items or issues. Blog posts appear in the following (reverse alphabetical) order, which may differ from the chronological order in which the posts were originally made:

  1. Wild birds (LAST)
  2. War
  3. Science & Technology
  4. Politics
  5. Latin America
  6. Culture & Travel
  7. Canaries ("Home birds")
  8. Baseball (FIRST)
