Hi, it looks like Rob Matson has kindly updated the list of failed Iridiums in his Iridium flare predicting program iridflar. He also seems to have modified the list of cities skymap.cty. The new zip file is available from ftp://ftp.satellite.eu.org/pub/sat/programs/ibmpc/. You can get either flare164.zip or iridflar164.zip; these 2 files are identical. Best, Mark
