Note that my estimates were very speculative, based on limited reports.
An experienced observer in Champaign reported it to his west following
an approximately 45? angle of descent. So it doesn't sound like this was
very shallow.

I haven't read anything (yet) to suggest that any of the more southern
witnesses saw the meteor near them. It is not unusual to see a meteor
150 miles away; in the absence of other evidence, my thinking is that
the object was fairly low at Beardstown, didn't travel much farther
south, and the witnesses to the south were simply seeing it far to their
north. The speed and duration suggest a ground path perhaps 100 miles
long. More reports would be good.

Following the Russian rocket body decay over Colorado last month, Fox
news called it a "Quadrantid meteor shower from an extinct
constellation".
