Report in PDF format. Left-click to read in your browser or Right-click to download. Narrowband photometric observations of comet Hale-Bopp (C/1995 O1) between 25 July 1995 and 15 February 1997 indicated gas and dust production rates of 20 and 100 times greater, respectively, than observed at the same heliocentric distances for comet P/Halley in 1985.

The Tau Herculid meteor shower and Comet 73P/Schwassmann–Wachmann 3
Report in PDF format. Left-click to read in your browser or Right-click to download. The Tau Herculid meteor shower has not shown any appreciable activity since 1930. However, it is associated with Comet 73P/Schwassmann–Wachmann 3, a Jupiter-family comet that split in 1995. The fragments will pass near the Earth on 2006 May 13, and could produce an outburst of the Tau Herculid shower.
