After yesterday’s surprise outburst comet 17/P Holmes continues to put on a great show. This object is highly dynamic and you can watch it move day-to-day with just the naked eye. Between yesterday and today the comet has moved noticeably closer to the star Alpha Persei and has also definitely brightened. Yesterday Holmes and the star Delta Persei looked to be the same brightness, today the comet is definitely brighter than the star. I’d estimate it’s brightness at about Magnitude 2.5.

I’ve been following the comet with my trusty 10x50mm binoculars and the changes are even more spectacular through them. Yesterday Holmes looked like a star, a point of light with no noticeable coma or tail. Today, it looks like a compact globular cluster with a bright core. Yesterday I didn’t really notice a colour buy today it’s clearly yellow. I’ve never seen an astronomical object change so much so quickly. I hope we get to watch this fascinating object evolve for a few more days to come, however, the weather forecast for us here in Ireland is not looking good :(.

I’ll leave you with a scan of my record of today’s observation of the comet:
