Upcoming predicted passes for the night of 15 April:
USA 186, max mag 2.5 while moving SE to NE (max altitude 32˚NE at 8:26pm).
---This is an American military satelliate. It will emerge from the Earth's shadow in Corvus, cut through Virgo then go over Arcturus and below the Big Dipper.
the Abrixas rocket, max mag 2.0 while moving NW to SE (max altitude 69˚SW at 8:36pm).
---This rocket launched a German X-ray detector in 1999. It will cut through Auriga and Gemini, then go between Leo and the Winter Triangle.
Fregat/IRIS, max mag 2.2 while moving SE to N (max altitude 67˚NE at 8:44pm).
---This is an Russian demo satellite with inflatable panels. It will cut through Leo and the Big Dipper.
Hubble Space Telescope, max mag 2.0 while moving W to S (max altitude 28˚SW at 8:56pm).
---It will pass just under Rigel and Sirius, then fade into the Earth's shadow before reaching Corvus.
the Resurs 01 rocket, max mag 2.4 while moving NE to N (max altitude 39˚NE at 9:30pm).
---This Zenit 2 launched with its payload in November 1994. It will exit the Earth's shadow under the Big Dipper, then pass under Polaris.

Here is the NOAA forecast for 9pm CDT...
precipitation potential, 0%
sky cover, 20%
relative humidity, 53%
temperature, 14˚C
surface wind, NE 8 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "average" (3 out of 5) and the seeing rating will be "poor" (2 out of 5); this is an excellent forecast; what few clouds there are should go away as the night goes on, and the transparency may improve around 4am.

Here is the NOAA forecast for 9:15pm CDT...
precipitation potential, 0%
sky cover, 12%
relative humidity, 74%
temperature, 21˚C
surface wind, NE 5 km/h

Danko's Clear Dark Sky states that until 1am (about the time the relative humidity reaches 90%) both the transparency rating and the seeing rating will be "average" (3 out of 5). This is an excellent forecast!

Upcoming predicted passes for the night of 20 April:

---This is a Russian remote sensing spacecraft. It will cut through the bowl of the Big Dipper and the hind quarters of Leo.
SeaSat 1, max mag 2.4 while moving NE to SW (max altitude 77˚SE at 8:26pm).
---This Earth-observing satellite had an electrical short just a few months after its 1978 launch. It will cut through the handle of the Big Dipper and the head of Leo.
an Atlas-Centaur rocket body, max mag 1.0 while moving NW to SE (max altitude 65˚NE at 8:41pm).
---This rocket left Vandenberg in September 2012. It will just clip the corner of the Big Dipper then pass under Leo.
Fregat/IRIS, max mag 2.4 while moving S to NW (max altitude 73˚W at 8:54pm).
---This is an Russian demo satellite with inflatable panels. It will exit the Earth's shadow due south, then pass between Leo and Gemini, then between the Big Dipper and Auriga.
H-IIA rocket body, max mag 2.2 while moving S to NW (max altitude 71˚SW at 8:59pm).
---It will pass over the Winter Triangle, Gemini and Auriga.
Chang Zheng 2C rocket body, max mag 2.5 while moving NE to S (max altitude 73˚SE at 9:10pm).
---It will cut through the handle of the Big Dipper and the body of Leo.
Cosmos 1825, max mag 2.1 while moving N to NE (max altitude 76˚NE at 9:21pm).
---This is a defunct Soviet intelligence satellite. It will fade into the Earth's shadow right after passing over the Big Dipper.
the Resurs 01 rocket, max mag 2.2 while moving NW to NW (max altitude 54˚NW at 9:50pm).
---This Zenit 2 launched with its payload in November 1994. It will exit the Earth's shadow just west of the Big Dipper and move down toward the horizon.

Remember, the lower the magnitude number the brighter the object.
To obtain a skymap for each visible pass, I suggest Chris Peat's Heavens Above website; you will have to enter your exact location.

Between 8:10pm and 9:50pm there will be at least ten visible passes of non-Starlink objects through the Baton Rouge skies. Please use Chris Peat’s Heavens Above site to generate a timetable for your specific location.

From 8:25pm to 10:10pm Thursday the 30th, there are four passes predicted to be mag 2.5 or brighter. Please consult Chris Peat's Heavens Above for particulars. Experiment: from your location can you see passes as dim as mag 3.0?

precipitation potential, 0%
sky cover, 8%
relative humidity, 61%
temperature, 22˚C
surface wind, S 3 km/h

Danko's Clear Dark Sky states that at this time both the transparency rating and the seeing rating will be "average" (3 out of 5). If the forecasts hold, there will be excellent conditions from nightfall to about 3am!

The list for Saturday night will be posted tomorrow at about lunchtime.

By the way, note the lists for the last few evenings. It will be obvious that the same objects very often visit Baton Rouge over and over again, like a good friend. Can you set a personal best for the number of times you catch the same satellite or rocket body paying a visit?

sky cover, 23%
relative humidity, 71%
temperature, 22˚C
surface wind, S 10 km/h

Danko's Clear Dark Sky states that at this time both the transparency rating will be "too cloudy to forecast" (0 out of 5) and the seeing rating will be "poor" (2 out of 5). This is disparate information, so it's hard to discern what the viewing conditions will be tonight.
