Astrocomet
Comet 17P/Holmes....
What a sight up there in Perseus-magnificent, does this Comet have a reactive core that when it gets close to the Sun the chemical composition inside it flares up and throws out or vents more gases-the same thing happened in 1892 which led to its discovery, if it is 1.62 au from the Earth (245 million km/further away than the Sun) the whole Comet from the core as well as venting gases must be almost as big as the Moon to reports that have put it at 3 quaters of a million miles across to the outer nebulous regions, there are reports that the total brightness is unsure but at its flare up on the 24/10 estimates put it at Magnitude 10 although this has now stabilised to around Magnitude 2.3 to 2.5 and how bright it will get now is also unsure, Observing it through my 20X100 binoculars the central Coma looks like it is under some drastic changes venting out gases to cause the almost circular nebulous outer region-it looks to me vaguely a yellowish colour with a slight hint of orange but this could have been the streetlighting interferrence in my area causing this, an amazing sight even with small Binoculars and much worth going out to have a look at.

The Comet is visible in the North East after dark about halfway up in the sky-much better to locate with Binoculars-it looks like a small white spot in the sky but unmissable-
GOOD CLEAR SKIES......
