    I went out tonight to try and spot it for the 3rd day in a row, but tonight I had no luck. This isn't to say it wasn't there, but I live in a suburban neighborhood with houses around me. So, since on the 2nd day it was farther South than the 1st, maybe today it was even farther South behind the house behind me. I did check out front to see if it was farther North but couldn't find it there, either.

    To clear some things up,

    1. It certainly was no aircraft. As my username implies, I'm a pilot and I'm well aware at what aircraft look like and how they should appear. What I'm looking at is a very bright point of light, very similar to what Venus looks like when you view it. It's even about the same size (larger than a small point like a star).

    2. It wasn't an iridium satellite flare since a) it's not a streak (flare), but rather a steady point of light and b) flares require movement (which is what makes it appear as a flare) and this had no apparent movement.

    3. As I just stated above, even though in my OP I said there might have been movement, I really don't think there was. IF there was, it was the very slightest, only a few degrees/minute. However, it appeared to be stationary.

    4. As stated above, the object was a little farther South compared to the first night, but if you were to draw a line connecting the two spots, it would appear to be on the same path or trajectory, not any farther East or West.

    Here's another question.. The average distance between the Moon and the Earth is 238,857 miles. The average distance between the Earth and the ISS is about 220 miles. Both of these stayed illuminated the entire time they were in the sky (the ISS came out at a later time after I saw the bogey object on 9/5). So, assuming this could possibly be a geosynchronous satellite, which is aprox. 20,000 miles above the Earth, how could something like that (which is in between the ISS and the Moon) only stay illuminated for a couple minutes and then disappear, whereas, again, the ISS came out later and lower and was illuminated the entire time?

    Oh, and btw, to be more specific of where I'm at, I'm in South Arlington, TX, right between Dallas and Fort Worth.

    I was outside between 1900 and 2300 and saw nothing unusual. You say the second time you saw the object it appeared to be further south that would rule out a geosynchronus satelitte would it not? I have no idea....chris

    The ISS and satellites do not necessarily stay lit the entire time. They can change in brightness, or disappear all together.
    Im guessing it was a satellite/ISS

    Last night I did not see it either. Sunday and Monday nights I did. I'll check tonight again as well.

    It was NOT the ISS as I've already stated I viewed the ISS after the object in the sky. The ISS moves across the sky and its movement is very obvious. This object appeared to be still.

    As far as whether it's a geosynchronous satellite or not...idk. I've read that because it's on an inclined orbit (rather than over the equator which would make it a geostationary sat) it does not stay in one spot but rather covers a figure-8 track over the course of about 24 hours. But to someone viewing it from the ground, it would appear stationary (maybe because it's moving so slow in relation to the Earth?).

    OK-- take a look at this screenshot of Stellarium--- note what is following the sun right now (location in Stellarium is Dallas, Texas)-- could you be seeing Venus just as the sun sets right now- ??

    Screen shot:

    You would need a CLEAR SHOT toward the West -- to be able to see it VERY low on the horizon just as the sun set.

    Well straight up right now is about where the bright star Vega happens to be.

    Yep, I've looked at Vega with that app I have on my phone. Vega is right where it should be, whereas, whatever I saw showed nothing in that location. This object appears even before Vega is visible. Not only that, Vega is in about the same spot every night. This object changed position from Day 1 to Day 2. And, Vega isn't nearly as bright or as large as this light that I saw. Oh, and Vega twinkles, this didn't. I don't mean to be difficult, it's just that I think I've discounted all the obvious stuff..

    To add to my previous reply, NO stars were visible both nights I witnessed it (to the unaided eye under city skies, anyway..). This was the only thing visible in the sky except the moon (the Sun had just set below the horizon but the skies were still relatively light). Even the brightest stars, such as Vega, came out about 10-15 mins after this bogey light had already appeared and disappeared.

    All I can tell you is that we have over 400 amateur astronomers right here in the Dallas area-- not one of them have reported seeing anything unusual in the sky.

    If it's not Venus, and not Vega which would have moved about 15 degrees over a 1 hour period-- and it was not the ISS which would have been visibly moving and very bright-- and not a geo- stationary satellite then ???

    Your other question -- a satellite will stay visible (unless it is tumbling) until it moves into the shadow of the Earth-- there is software available that will predict how long the sat will be visible--

    Most of the time they appear suddenly at some point in the sky and then fade out-- at various distances from where they first appeared. Usually the sat can be seen moving slowly against the background of stars.
