Entry for October 28, 2007
I just observed comet Holmes again and it appears to have a double nucleus! If so, that would explain the explosion that caused it to brighten so suddenly. Observing from my back yard at 7:55 PM with a small 4 inch refractor at low power, I could swear I saw TWO starlike nuclei inside the coma, but it could be that one of the starlike points was a background star. I am hoping that other astronomers will be able to confirm this. Stay tuned!
