(meteorobs) meteorite, heavens above questions

[cHArlie]

Do meteorites consistently get an electric charge(positive/negative?) 
when they enter the atmosphere?

at 10:15pm CDT  I saw a really bright light coming from WSWW to ENEE, 
later I went to Heavens Above to see if it was the ISS

I only got hits from 19:11 to 20:52, since this is supposed to be 12 
hour prediction, why only 1 hour 41 minutes?
What am I missing?
Thanks, Charlie
