Satellites and their shadows in transit across the face of Jupiter. These exceptionally high-quality images show some of the recent multiple satellite transits, and even resolve the dark reddish polar caps on Io. The satellites and shadows are projected on the equator, and are identified by labels below each image. South is up. See the article on page 128.
Top: 2003 January 18, 00.43 UT, CM1 = 98.9, CM2 = 226.7; Damian Peach (Tenerife). This was taken during the remarkable triple transit. Callisto (IV) is dark, Io (I) has a bright equatorial region, and Europa (II) is just discernible because of its dusky equatorial region.

Notes and News
Main articles
I will describe how and why the patrol started in 1976, including earlier events that persuaded key individuals that the time had come for a team approach to searching for novae. The aims of the patrol will be discussed and how these have changed over the years, which has necessitated some rethinking of the techniques employed. (12 pp)
