Iridium flares end with replacement satellites

Click For Summary

Discussion Overview

The discussion revolves around the phenomenon of Iridium flares, their impending end due to satellite replacements, and the implications for sky observation. Participants share personal experiences, technical details about visibility, and speculate on future developments in satellite technology and advertising.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant reflects on their experience observing Iridium flares, noting they were brighter and lasted about 10 seconds, emphasizing the need for accurate geographical positioning to see them effectively.
  • Another participant expresses relief at the end of Iridium flares, describing them as a nuisance that interferes with meteor observations.
  • Some participants discuss the potential for new satellite technologies to create artificial flares for entertainment or advertising, referencing existing concepts like "moonvertizing."
  • There is a mention of the challenges of observing celestial events from urban areas, with one participant sharing their experience living in a city with significant light pollution.

Areas of Agreement / Disagreement

Participants express differing views on the value of Iridium flares, with some appreciating their beauty and others considering them a nuisance. There is no consensus on the future of artificial satellite flares, as opinions vary on their desirability and potential applications.

Contextual Notes

Participants reference specific magnitudes for visibility and the impact of urban light pollution on astronomical observations, indicating a dependence on local conditions for observing celestial phenomena.

Who May Find This Useful

For a long time I'd heard about Iridium flares, but not taken much trouble to see one. This week I took advantage of the uncommon spell of clear nights to pop out and look at a couple.
Not quite what I'd expected, so I went to look into them a little more. One of the things I discovered is that I nearly missed them. Soon they will be no more. (end of 2018.)

I'll leave others more expert than I to supply any more info, but suggest anyone who wants to see one, gets on to Heavens Above and takes advantage of their next anticyclone.

Somewhere over the rainbow, somewhere far...

I've seen a couple of high magnitude, and those were pretty impressive . Very bright and lasting about 10 seconds. You need to have your longitude and latitude entered accurately, the swath that the reflection hits is narrow and the brightness drops off sharply.

But a - 6 ~ - 8 mag in your area, on a clear night will be rare.

I couldn't be happier :smile::smile::biggrin:

They are a BL@@DY nuisance ... look too much like meteors and screw up my nice meteor observations and photos

Is that the first time I've seen you smile?:rolleyes:

You should try living in a big city. There's not much to see in the sky dimmer than magnitude 1 this time of year. Good job I live near the airport.

haha you obviously don't follow me or know me well enough on PF …. go look at my posts in the lame and science jokes sections :smile:

I do, Sydney, Oz is over 5 million people and I am deep within the red zone ……

each of those 3 sites is around an hour's drive from home, they are not great, but I can do some imaging as long as it is in the 1/2 of the
sky in the opposite direction to the city centre
To really get out of the city sky glow, I need to travel up to 2 hrsDave
