I just witnessed a train of Starlink Satellites.☹️ Walked out in my backyard to check out if the sky was clear to setup my imaging rig. Looking north I saw a stream of satellites moving west to east 35 degrees above the horizon. About seven in a row, then another would appear from the Earths shadow, and another, and another...... It was about 9 pm local Mountain time.

Did anyone else see this?

They just launched, they'll be below the naked eye visibility threshold within the next few days.

So when will they be below telescope visibility threshold? Within the next few weeks?

Yep. I'd just stepped outside to take some SQM-L readings, to see if the haze that's been bugging my area for the past several weeks had gotten any better. A bright moving object to my NNW at about 60° altitude caught my eye... and as I looked, a line of dozens more followed right behind it, headed toward my NE horizon. Most of them were separated by about 1.5-2 degrees, but a couple of them were less than a quarter-degree apart. I lost count at sixty.

 

This was the first time I've seen them... and I have to say that I was neither pleased, nor impressed. Quite the opposite, in fact... and like PirateMike, my personal preference would be that they all fade into oblivion.

Unfortunately, we astronomers are ~the little people~. They will humor and patronize us, not unlike the 1950's TV commercials telling my parents that cigarettes were good for them. By time the smoke cleared, the executives and politicians were happily retired and gone from the scene. Some things never change.    Tom

Maybe please some of you make effort to learn just a tiny bit more about things before you over-react..

These results OF VERY RECENT launches all described above aren't at their final spacing and orbit.

The launches are happening at fast pace, promised to make deadlines to the FCC at initial open mega-constellations approval hearings----you know, the ones NONE of you complainers were at to voice and object to them before approval?

 

At least initially Elon Musk offered acknowleged to stargazers tweeting out "they wouldn't be bright, and anyways the ISS is bright because it has lights on it."foreheadslap.gif  (May 2019).

SpaceX has done a very good job cooperating with the AAS and IDA to reduce satellite albedo and continues to do so. Attacking them with vitriol makes us all the more easy to patronize as Tom said.

I saw that same string last night.  The sky was not fully dark yet, i was looking at something in the southern sky and when I turned around and glanced to the north I saw them at maybe 40 degrees and traveling basically west to east but slightly to the north.

 

I would guess that 40 or so were visible at once.  I thought about calling my neighbor, I think he would have enjoyed it  but my phone was in the house.

 

I would also prefer that they fade away.  I'm not complaining, I'm stating a personal preference. That's something very different..

Isn't there enough light pollution on the ground!? Hey! Let's destroy the night sky, so everyone can get MTV! And post pics of themselves doing nothing on Facebook!!

Actually, the bulk of Starlink’s market is rural folks who need Internet for work, emergencies, etc. Ironically this demographic includes some astronomers. With the sats below magnitude 6 or 7 the bulk of the time, they’ll affect some research and be annoying to process out if you image shortly after astronomical twilight ends, but in general they won’t affect the aesthetic to the naked eye and for something like 90% of amateurs and researchers are about as much of an issue as aircraft... and nobody calls for shooting planes out of the sky because they ruin astronomy.

Rather than complaining about an issue that we can do basically nothing about, if light pollution bothers you you should join the IDA and learn how to help with dealing with the (far bigger and more destructive) issue of regular terrestrial sky glow. There’s an IDA social this afternoon....

Folks, let's please keep things civil here.

 

Complaints are OK, but name-calling is not.  I would much prefer to let this discussion continue (as others before it have), but if we descend into vitriol and mud-slinging here, I'll have to lock it up.

They'll be below telescope visibility threshold when they go behind the shadow of the Earth like they are for most of the night.

This is much ado about nothing for amateur astronomers. Light pollution has been & will continue to be an exponentially greater problem for us.

But for professional astronomers, this is a big deal and a growing serious problem.

Getting back into observing after a decade away. Moved to a much darker home with good view of the sky.

 

Just had my first experience of seeing a train of Starlink sats. frown.gif

They just recently launched and will be below magnitude 7 shortly.  Not much to worry about.

Saw two sets tonight.  The first one was not predicted at heavens-above.com.  It was from about 9:32 PM to 9:41 PM from SW to NE passing near Castor and Pollux, with many about as bright as the two stars.  Had to have been at least 60.

 

Then around 9:54 PM saw the set predicted.  It came from NW passed below Polaris heading SE, but disappeared a ways east of Polaris.  These were much closer together and looked like a line at times.  They were about 3rd magnitude.  Definitely fainter than Polaris.  Only lasted a minute or two.

Does anyone have a clue what the first batch was?  I cannot find a Starlink launch to match up to it.  These had to be much lower than the second set suggesting a more recent launch.  Maybe something other than Starlink?
