This thread will be used to attempt to alert for the brighter visible passes of...
*The International Space Station
*Starlink strings
*the recently-launched BlueWalker 3
*Tiangong
...among others.
These alerts will not be comprehensive and their predictions should be confirmed with a second sources such as Heavens Above.

Re: Observed Passes of Satellites, Rocket Bodies (etc.) in 2023
HRPO's first Edge of Night twilight viewing session of 2023 will take place on Friday 10 March from 5:30pm to 7:30pm. The viewing session has no admission fee.
Current predictions indicate four regular visible passes during this period, ranging in magnitude from 2.2 down to 0.2. Participants will also have a change to glimpse the elusive A-class magnitude -0.6 Canopus, which will culminate at a challenging seven degrees.

The front gate and main building will be open at 5pm.
Below is the NOAA forecast for HRPO's planned viewing time of 5:30pm to 7:30pm...
precipitation potential, 4%
sky cover, 41%
relative humidity, 71%
temperature, 22˚C
surface wind, N 12 km/h
Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "below average" (2 out of 5) and the seeing rating will be "poor" (2 out of 5).
Sunset is at 6:09pm CST. Twilight ends at 7:29pm CST. One telescope will be used. Targets include the Pleiades Star Cluster, the Orion Nebula and Mars.

HRPO's second Edge of Night twilight viewing session of 2023 will take place on Friday 7 July from 8pm to 10pm. The viewing session has no admission fee and is for ages six and older.
Current predictions indicate eight regular visible passes during this period, ranging in magnitude from 2.5 down to 0.8. Participants will also have a change to glimpse (binocular required) a whopping fifty-one STARLINKs in three separate chains.

Monday 10 July, 9:29pm to 9:36pm CDT
International Space Station
magnitude -3.9
The ISS may reach a whopping -3.9 in brightness for some lucky spectators. It will move from southwest to northeast, reaching an angular altitude of seventy-five degrees as it passes through Serpens on its way to Hercules. Sadly the current NOAA forecast gives a rain chance in excess of thirty-five percent. [This is a generalized prediction for the HRPO area. Please confirm with an independent source.]

Hubble Space Telescope
magnitude 1.8
Hubble may have a good pass. It will move from southwest to east, reaching an angular altitude of sixty-three degrees as it passes through Ophiuchus then under Altair. [This is a generalized prediction for the HRPO area. Please confirm with an independent source.]

International Space Station
magnitude -3.9
The ISS may reach a whopping -3.9 in brightness for some lucky spectators. It will move from southwest to northeast. It will exit the Earth's shadow just east of Canis Minor at an angular altitude of eighty-three degrees. Be cautious; NOAA is currently stating "haze/smoke" for the HRPO area.

Below is the NOAA forecast for HRPO's Edge of Night viewing time of 4:45pm to 6:45pm CST...
precipitation potential, 47%
sky cover, 95%
relative humidity, 98%
temperature, 21˚C
surface wind, NE 11 km/h
Danko's Clear Dark Sky states that during HRPO's viewing time both the transparency rating and the seeing rating will be "too cloudy to forecast" (0 out of 5).
Sunset is at 5:10pm CST. HRPO be open from 3:15pm to 5:15pm CST, just to take visitors who are obtaining school extra credit, registering for a program or purchasing an item.
