15 June 2020 Predicted Visible Passes

Post by Christopher K. »

There are three visibles passes brighter than 2.5 predicted for this evening; the passes begin at 8:44pm and end at 9:54pm. I do not recommend attempt to spot them as the forecast doesn't call for excellent or very good skies. Please go to Heavens Above to generate a list if you are interested anyway.

Here is the NOAA forecast for 10pm CDT tonight...
precipitation potential, 1%
sky cover, 44%
relative humidity, 67%
temperature, 27˚C
heat index, 28˚C
surface wind, W 3 km/h

Danko's Clear Dark Sky states that all throughout the night the transparency rating will be "below average" (2 out of 5) and the seeing rating will be "average" (3 out of 5). If the predictions hold there will be one hour of good conditions from skygazing--from 10pm to 11pm. The transparency becomes "too cloudy to forecast" from 11pm to 2am; the relative humidity reaches ninety percent at 4am.

There are three visibles passes brighter than 2.5 predicted for this evening; the passes begin at 9:20pm and end at 10:24pm. I do not recommend attempt to spot them as the forecasts are yield disparate data. Please go to Heavens Above to generate a list if you are interested anyway.

Here is the NOAA forecast for 10pm CDT tonight...
precipitation potential, 0%
sky cover, 12%
relative humidity, 58%

Danko's Clear Dark Sky states that all throughout the night the transparency rating will be "too cloudy to forecast" (0 out of 5) and the seeing rating will be "average" (3 out of 5). If the predictions hold conditions will improve overnight, with the best transparency from 2am to 3am.

Summer 2020 "Edge of Night" Viewing Session

Post by Christopher K. »

The second of three Edge of Night twilight viewing sessions always takes place the Friday of Independence Day week. For 2020 that will be Friday 3 July from 8pm to 10pm. We do know that the waxing gibbous Moon will be available, and visible passes of five defunct rocket bodies are predicted for between 8:30pm and 9:55pm Central Daylight Time. Additionally there will be three Starlinks passes at magnitudes at least as bright as 3.5. The event has no admission fee and is for all ages. HRPO personnel encourage patrons to bring binoculars. Phase 2 Guidelines will still be in effect.

The International Space Station will pass over from about 9:16pm to 9:20pm, passing from NW to S; the predicted magnitude is -3.1. Please go to Heavens Above to generate more accurate information for your location.

Here is the NOAA forecast for 9:30pm CDT tonight...
precipitation potential, 0%
sky cover, 28%
relative humidity, 65%
temperature, 29˚C
heat index, 32˚C
surface wind, NE 3 km/h

Danko's Clear Dark Sky states that both the transparency rating and the seeing rating will be "average" (3 out of 5). If the predictions hold the tranparency and humidity will deteriorate, the seeing will improve and the sky cover will stay about the same.

We had deteriorated skies earlier, so no viewing of passes tonight! However, we should have good skies between midnight and 2am, with above average transparency and excellent seeing.
