Comet Brewington position discrepency!

[Gasman]

Hi

I`d like to have a go at finding Comet P154 Brewington but this web site http://in-the-sky.org/cometephem.php?obj=0154p gives its position as RA 21h59m27s Dec -01°48'00" but downloading the latest Comet data for Cdc puts the comet at RA 16h 51m 40s   Dec -39 28` 31" ?? These are just so far apart so which is the correct one please?

Thanks

Steve

The correct one is whatever this website says!

Could there have been confusion between comet 154P Brewington and asteroid (5799) Brewington?

I think Themos is right. Your latter co-ordinates look good for asteroid Brewington, not the comet. Also, there are two comet Brewington's! 154P is in Aquarius, and C1996 N1 is in Orion.

Thanks chaps its the first one. Think there must have been a mistake with the Cdc Comet data download as I`ve just tried it again and the entry isn`t there now even the actual one i want?
