What is up there in between Cassiopeia & Lacerta?

It is like a comet, no nucleous visible, 4x bigger and much brighter than Holmes was last month. "Pointed" at the Sun.

It wasn't moving. It was at my zenith (7:00pm EST). It is cloudy here now.

A Ufo ?

A Ufo ?

It is until I find out what it is!

Yup ;)

Can you take pictures of it with your telescope ?

No, can't take pictures with telescope, havent had the telescope out in years. If the clouds break maybe I can take a picture with my camera if I can hold it still enough. Not likely though.

It is quite bright.

Will do, clouds look they'll be around for a while.

Thanks for the "welcome".

I checked out Holmes, it is still visible to the naked eye if you know where to look..

That kind of sighting is usually a contrail from a jet.

a simple solution to your camera woes would be to mount a screw to the hour spindle of an electric clock.
solder a nut in a hinge where the hasp passes through.
thread screw through nut a couple of turns then mount hinge in a suitable place.
there will be details you need to figure out but the basic drive will be there.

Hum,
if it was a `small bright cloud ` it could be a fuel dump from a classified satellite that was launched at 2205 UT today.
It would have been visible from northern America after 23:30 UT (6:30 pm EST)

or it could be something else....

Well, it is gone. So much for the comet theory. Some better details about what it looked like:

It was round and fuzzy, within the center it had a more compact/less fuzzy area in the center, that was like a line pointed toward where the sun was, over the horizon. It was not lit from the ground, it looked like it was either back-lit, or luminous itself. It had a bluish tint, as if it was from a long exposure shot of a nebula.

The sun was down a long time when I saw it, and it was not moving in relation to the stars, although the clouds were.

As far as being a contrail, its roundness, and it being so late leads me away from that idea. But I have no better idea, unless there was some sort of outgassing of a rocket out there. Any launches lately?

I'm sure you all think I'm a crank now, I'd think so too.

So I guess this is my first UFO. Good thing it didn't involve any probes.

Well, if it is classified, how do you know about it? :D

Sounds like it could be it.

Got a link?

I guess "classified" means that the payload/sattelite is classified, not the launch.

Would it have been "Atlas 5 • NROL-24"?

What website did you use to determine that the fuel dump would have been visible over North America?

Snash, you are very much not a crank, because you ask for and consider alternative explanations.

Hum,
Yeah, details about the payload are classified, but it is suspected that it will replace an aging SDS communications satellite; therefore a Molniya orbit can be plotted. And it was suspected that there would be a `standard` practice fuel purge about 1 hour 30 minutes before it enters a transfer orbit (to final station orbit).

According to spaceweather.com the predicted fuel dump from the upper stage of the Atlas rocket (ie single-engine Centaur upper stage) was indeed spotted by many observers.
It seems the blue luminous `cloud` lasted for about 50 minutes and was even spotted from the UK (See the previous orbit 68kb IMAGE).

Seems like a probable explanation.

That was it!

I've spent quite a few years stargazing and that was the best unexpected event I've seen.
