Comet C/1998 C1 (Williams)

This comet became visible from the UK as a morning object during 1998 December. David Strange imaged it on 1999 January 22.

Comet 52P/Harrington-Abell

This comet had a significant outburst in 1998 July which boosted its magnitude to around 12. David Strange imaged it on 1999 January 22.

Comet C/1999 H1 (Lee)

This comet was descovered in the far south but it was still quite a nice object once it had travelled far enough north for Denis Buczynski to image it. This image was obtained on 1999 August 29.01 using a 60s exposure with the 0.33m Conder Brow Automatic Telescope.

Comet C/1999 S3 (LINEAR)

Images by Denis Buczynski obtained on 1999 October 10 and Nick James obtained on 1999 October 11 show a short tail.

Comet C/1999 S4 (LINEAR)

This comet could reach naked-eye visibility in mid 2000. Shortly after discovery it was a faint object as shown in this image taken on 1999 October 13 by Martin Mobberley using his 0.49m, f/4.5 Newtonian and an SX camera. The comet had brightened somewhat by the time Martin took this image on 1999 December 28.

Comet 141P/Machholz 2

This comet split into a number of components. Martin Mobberley imaged component A on 1999 December 29. He imaged it again on 2000 January 9. He writes: "[This image is] my last for a while as the Moon will be a problem for the next two weeks. Hardly an inspiring shot! I've failed to image component D yet, possibly the low altitude murk is the main culprit."
