(meteorobs) IMO Visual Meteor Report (GRALE), Night of 19-Feb-2001
What follows is the first of four email-format reports from the wonderful
observing sessions I got to do at this year's Winter Star Party last month,
in the unique and beautiful Florida Keys... I cc these reports to the list
as a sample of the IMO Reporting style, should folks have any questions!
Note that plotting charts for the three nights spent plotting are to be
mailed via postal mail after this.
Clear skies!
