C/2008 A1

Rob McNaught has racked up #40 with a newly discovered comet, C/2008 A1 McNaught will come to perihelion in November, 2008, and reach 9th Mag possibly and will be a southern hemisphere object.

Congrats again Rob!

C/2008 A1 McNaught

The preliminary orbit has it passing through the Southern Cross as it comes closest to Earth and reaches its brightest, so very appropriate for an Australian discovery.

Touch and go, but at any rate, it'd be an early morning stint so moon would be no problem, and good viewing for those further south! Interesting object!

C/2008 A1 McNaught

A couple of things to bear in mind. It is closest to the Earth mid September and never gets within the orbit of Mars so the date of perihelion in November may not be a big deal. In fact it will probably be fading by then. Also this orbit could change quite a bit yet.

Latest orbit changes things a bit, makes it a better object for us in September, perihelion now late that month.

Magnitude looks pretty steady right through September, mid sevens, and nicely placed in the evening sky for us, at 34S anyway. A good binocular object.
