Abstract

The International Chart Working Group (hereafter termed ICWG) is a team of expert chart and sequence makers drawn from the American Association of Variable Star Observers (AAVSO), The British Astronomical Association Variable Star Section (BAA VSS), and various other individuals that set out in 2000 to tackle what was then a chaotic situation with regards to sequences. This presentation is a summary of the group's work undertaken primarily during the years 2000-2003.
