Observed Passes of Satellites, Rocket Bodies (etc.) in 2019

Post by Christopher K. » February 8th, 2019, 4:24 pm

The first of three Edge of Night twilight viewing sessions take place the Friday before the change from Standard Time to the questionably-helpful Daylight time. That will be Friday 8 March from 5:30pm to 7:30pm. Below is the planned schedule...
6:08pm = “civil twilight” begins (search for crepuscular rays)
6:33pm = “civil twilight” ends; “nautical twilight” begins
7:01pm = "nautical twilight" ends; "astronomical twilight" begins
7:28pm = "astronomical twilight" ends
The event has no admission fee and is for all ages. HRPO personnel encourage patrons to bring binoculars.

PREDICTED FLARE
Iridium 97
Date: Friday 15 February
Time: 6:40pm CST
Altitude: 55˚
Azimuth: NNE


I won't write much more, but I will attempt to post any remaining predicted Iridium Flares brighter than magnitude -1.5. Anyone interested in spotting them should always go directly to Heavens Above to generate a more accurate sets of parameters based on location...

I won't post predictions more than seventy-two hours out.

The NOAA forecast states there will be a ninety-three percent cloud cover during the Edge of Night time span (5:30pm to 7:30pm). It is highly unlikely there will be any portion of sky available for any extended portion of time. HRPO personnel will supplement the planned outdoor activities with some meteorite displays (twilight fireballs are rare but possible) and a tour of the 20OGS, as well as an introduction to the three raffle prizes for this year's International Astronomy Day.
