Oumuamua was first detected by the University of Hawaiis Pan-STARRS 1 telescope on Haleakala, Hawaii, in October 2017 while the telescope was surveying for near-Earth asteroids.
Subsequent detailed observations conducted by multiple ground-based telescopes and the NASA/ESA Hubble Space Telescope detected the sunlight reflected off Oumuamuas surface.
Large variations in the objects brightness suggested that Oumuamua is highly elongated and probably less than 2,600 feet (800 m) in its longest dimension.
But NASAs Spitzer Space Telescope tracks asteroids and comets using the infrared energy, or heat, that they radiate, which can provide more specific information about an objects size than optical observations of reflected sunlight alone would.
The fact that Oumuamua was too faint for Spitzer to detect sets a limit on the objects total surface area.
However, since the non-detection cant be used to infer shape, the size limits are presented as what Oumuamuas diameter would be if it was spherical.
Using three separate models that make slightly different assumptions about the objects composition, Spitzers non-detection limited Oumuamuas spherical diameter to 1,440 feet (440 m), 460 feet (140 m) or perhaps as little as 320 feet (100 m).
The wide range of results stems from the assumptions about Oumuamuas composition, which influences how visible (or faint) it would appear to Spitzer were it a particular size.

The “Bill Clinton” comet?
It’s a Strange thing, but I have the feeling we should go and bargain with it.
Space giants keep sending their shit our way.
Speaking of stuff in the sky, I found a little (About 1”) pile of black ash on the hood of my Suburban this morning.
It didn’t look like someone put a cigarette out on it as there was no tobacco chunks and no damage to the paint.
It looks like it just floated down and softly landed there.
It’s ash. REALLY fine black ash.
Weird...
On intercept of Voyager 1?
Voyager 1's Back Thrusters Just Fired Up for the First Time in 37 Years [December 1, 2017]
Hmmmm.....

Who refueled Voyager 1 ?
First discovered:
The object was discovered Oct. 19 by the University of Hawaii's Pan-STARRS 1 telescope during a nightly search for near-Earth objects, NASA said. Astronomers are currently working to point telescopes towards the object to obtain more data. Once that's done, the information will be analyzed so scientists can determine more about its origin and composition.
So Voyager's thrusters were fired up two months later. More hmmm...
Whatever it is, NASA is fairly certain it's a unique object.

There was a report shortly after O was discovered of a similar object farther away. No further reports on that object I know about.
The name comes from the Hawaiian “oumuamua”, meaning ‘scout’.

Could be a bit of ash from the fires in California.
In Denver, though?
I remember St. Helens leaving ash after the eruption, but California is a bit more south for the usual weather currents to carry it here.
I know this was the spaceship guy who made all his followers think they were being taken to a comet but he does look an awful lot like Jeff Bezos.
I dont know you were in Denver. I was thinking it would be a possiblity ash might fall in the southwestern part of Colorado like Durango and cortez.
I always figured Marshall Applewhite was Marshal Mathers’ real dad.
