In McIDAS, west longitude is positive, not negative (historical artifact from
the very early days of McIDAS).  Because of this, your invocation should
have been:

IMGDISP G13/VIS27APR11 1 DAY=11117 TIME=19:02 20:45 LATLON=45 90 MAG=-10 -20 
REFRESH ='EG;MAP SAT'

The default for IMGDISP is to display the most recent image in the time range
specified.  If you want to display all of the images, you would run:

SF 1
IMGDISP G13/VIS27APR11 DAY=11117 TIME=19:02 20:45 LATLON=0 70 MAG=-10 -20 
SF=YES ALL=1 5 REFRESH='EG;MAP SAT'

NB: this assumes no more than 5 images in the time range specified; change the 
last frame number
in the ALL= keyword clause if there are more images.

Please review the built-in HELP for IMGDISP and/or the online Users Guide for 
more
information on how to run McIDAS programs.

re:
> Thanks!

No worries.

Cheers,

Tom
