New Comet SWAN In Evening Sky! was created by martinastro
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

Just made this based on the latest Ephemerides
www.irishastronomy.org/user_resources/fi...130196635-2005t4.pdf
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.
Cheers,
