I saw a UFO tonight

Out of interest, can anyone explain the illusion that caused my misperception of depth? At first I thought the light was a plane or a helicopter, it really did look close.

Past about 100 feet or so, the 'normal' method of determining distance (geometric convergence) isn't very good with human eyesight. So, the brain starts to use secondary estimators: Is something else in front of or behind it? How washed out are it's colors? How much of an angle does it take up (compared to similar shaped objects)? How bright is is? These are subject to pretty big errors when trying to determine the distance to a bright object too small to have discernible features.

My 2p: It's very difficult to estimate the height, depth and actual lateral position of an object in the sky - there is little to give a scale. For example, automated weather stations at airports report cloud height by using a laser and sextant. The beam is sent into the clouds and a sextant used to gain it's height and angle and thereby (using trig) to work out it's base.

The autokinetic effect is also something to be aware of - a stationary light in the sky will appear to move around in a dark or featureless environment. In fact, it has killed many pilots.
 
So they are disguising their ships as Jupiter now. I will note this in my log.
 
Venus gets seriously brighter than Jupiter at times. Enough so you can see it in the day if you know where to look and it's near it's brightest.

I've kicked around making a website that one can enter latitude and longitude and it will spit out instructions for locating Venus in the day including the best future days and times for viewing.

Hmm didn't know that.

What surprises me is that no cleaners, toilet attendants, train drivers, milkmen or famous criminals are reincarnated - it's only people with status that are reincarnated :rolleyes:

And amateur parlour magicians too by the looks of it.

The first volume of my study explains how telepathy,dreams work, then I illustrate the method by comparing a large number of historical persons telepathic communication (in real time) about themselves, and compare this with the article published in Encyclopedia Americana (1970). Except for one, Thucydides, all matched. In the Encyclopedia Brittanica I found a good match to what Thucydides gave about himself.
The second volume is about contemporary life both on earth and in the astral. A chapter is devoted to the Dalai Lama system of government, and where it failed its people; Islam, and where polygamy fails women; the Vatican and where it fails women, contemporary democracy and the not fail-proof electoral system. None of these pontificating but with a series of real life examples. Several examples of ordinary contemporary life.
When I became subject of a secret police investigation, I followed and recorded the participation of friends and foes serving as informants, yes, some are humble workmen, for others here reincarnation kicks in once again, as some of these informants have been know as the Apostles at the time of Christs. Who knew?
The Synopses for the entire work is posted on my website and also on my page in Scribe.com

Many moons ago I had a similar 'hovering' experience with Venus under conditions with very transparent night sky and no light pollution.
I however was keenly aware it was Venus and I had seen Venus many times before under night time conditions, however when light pollution (and lesser conditions) was/were present. This time, due to the excellent circumstances the planet seemed extraordinarily bright and the suggestion of it hovering was very very strong indeed.

Have you tried to compare your impression of the brightness (and the 'hovering') of Jupiter at that time with a later observation of Jupiter under different (more light polluted or less transparent) conditions?

On a related note:
Once driving on the South African platteland at night, I saw stars under extremely transparent conditions without any light pollution whatsoever.
I got out of the car and was overwhelmed by how many stars were visible, the constellations were unrecognizable.
The stars seemed so close, I felt I could easily touch them.

You could do the same for Jupiter, it can be seen during the day as well, with optical aid.
Mercury and especially Saturn will be challenging but can be done.

Even the brightest stars when the sun is not too far from the horizon can be done, even with a good 8x20 binocular.

Telescopically much more is possible.
