---This Zenit-2 launched with its payload in September 1993. It will exit the Earth's shadow just east of the Big Dipper.

Here is the NOAA forecast for 9:30pm CDT Sunday night...
precipitation potential, 0%
sky cover, 0%
relative humidity, 61%
temperature, 19˚C
surface wind, N 4 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "above average" (4 out of 5) and the seeing rating will be "average" (3 out of 5). If the forecasts hold, there will be excellent conditions all night long!

Upcoming predicted passes for tonight:
an H-IIA 202 rocket (Spacetrack #37159), max mag 0.5 while moving NW to E (max altitude 61˚N at 8:21pm).
---This rocket left Tanegashima in September 2010. It will pass just south of Venus then cut through the bowl of the Big Dipper.
International Space Station, max mag -1.4 while moving SW to NE (max altitude 23˚NE at 8:28pm).
---This first sections of the ISS went into orbit in November 1998. It will skirt the edge of Auriga.
the Resurs 01 rocket, max mag 2.1 while moving SE to N (max altitude 43˚NE at 9:24pm).
---This Zenit 2 launched with its payload in November 1994. It will exit the Earth's shadow quite below Arcturus, then pass under the Little Dipper.

Here is the NOAA forecast for 9:30pm CDT tonight...
precipitation potential, 0%
sky cover, 4%
relative humidity, 71%
temperature, 22˚C
surface wind, W 7 km/h

Danko's Clear Dark Sky states that all throughout the night the transparency rating will be "above average" (4 out of 5) and the seeing rating will be "average" (3 out of 5). If these forecasts are correct viewing conditions will be excellent until about 11:30pm.

NOTE: One will notice that the ISS passes lower than most predictions listed. I use a cut-off of thirty degrees above the horizon, as I believe many will have building and tree obstructions. However, the ISS is usually quite brilliant and so I will post ISS predictions down to fifteen degrees.
