With each passing night, conditions improve for spotting Superbird A
(#20040)
from the U.S.  Wednesday night, Sept. 9, shadow entry doesn't occur
until 3:09:50 UTC (Sept. 10 UTC).  This vastly improves the coverage
and flash brightness for the southwestern U.S.  Here are the estimated
UT peak times and locations:

Las Vegas, NV:  3:06  az 114, el 12.5
Tucson, AZ:  3:06  az 116, el 17.4
Phoenix, AZ:  3:06  az 115, el 16.0
Flagstaff, AZ:  3:07  az 117, el 15.6
Albuquerque, NM:  3:08  az 120, el 19.4
Santa Fe, NM:  3:08  az 121, el 19.6
Clovis, NM:  3:09  az 121.5, el 21.1
Salt Lake City, UT:  3:08  az 118.5, el 12.7
Denver, CO: (shadow)  az 124, el 18.1
Colorado Springs, CO:  (shadow)  az 123.5, el 18.6
El Paso, TX:  3:07  az 119, el 21.2
Amarillo, TX:  3:09  az 124.5, el 23.0
Austin, TX:  (shadow)  az 125, el 29.0
Dallas, TX:  (shadow)  az 128, el 28.1
Houston, TX:  (shadow)  az 127, el 31.5

If the time says "(shadow)", this just means that the estimated peak
time of flashes occurs after the satellite enters the earth's shadow.
So just start looking 6-8 minutes before shadow entry time.

Other locations may also see dim flashes just before shadow entry.
Favored states are:  Wyoming, Nebraska, Kansas, Oklahoma,
Arkansas, Louisiana, Mississippi and Alabama.  The east coast
just needs to wait one more day.  --Rob
