New Comet SWAN In Evening Sky!

Hi all

R. D. Matson (Newport Coast) and M. Mattiazzo (Wallaroo) have independently reported the possible visibility of an unknown comet in the publicly available images of the SWAN instrument aboard the SOHO spacecraft from Oct. 6, to 13. Both estimated the object in the range 9-11m. E. J. Christensen (Catalina Sky Survey) and R. H. McNaught (Siding Spring Survey) were then able to obtain confirmatory images. According to the first and very preliminary orbit comet C/2005 T4 (SWAN) passed perihelion on Oct. 2, 2005, at about 0.62 AU. According to this orbit the elongation will reduce further. The comet is an intrinsically faint object

The comet maybe already mag 10 -11 in Ophiuchus

Thanks for that update Martin

Wether we can see it or not is another thing!!

Just made this based on the latest Ephemerides

Bear in mind that xephem puts this at magnitude 13.94 tonight, so good luck.

Oh and since its a pdf you can zoom in all you like, you'll probably need to. Dots on the path are for midnight each date.
