Ladies and gentlemen for you viewing pleasure courtesy of Starrynight pro plus version 6, I would like to present the stars on the day Heathcliff died. I know that the pics aren't that easy to see but I am also going to include the written event section so you can be sure I am in no way fluffing the numbers or otherwise trying to mislead you.
Lets begin.
This quote below is taken from the software's event calender. The time is 1422 the day Heath died i.e 22 Jan 2008. The location is approx Central Park New York.
The important astro event is "The furthest Eastern Elongation of the planet Mercury as viewed from Earth".
"Mercury will reappear in your local sky (i.e New York) when it rises Tuesday, January 22, 2008 at 09:11 and will look best Tuesday January22, 2008 at 14:22."
Do I need to say anymore. What are the chances of that number popping up by chance. The number in question being the mythical 911..
From wiki..
At about 2:45 PM on January 22, 2008, Ledger was found unconscious in his fourth-floor loft apartment, at 421 Broome Street, in the SoHo neighborhood of Manhattan.[1][2] Emergency crews arrived soon after but were unable to revive him.[1][75] He was pronounced dead at 3:36 PM, and his body removed from the apartment, while crowds of onlookers began gathering outside throughout that night.[1][75]
So he was found by the masonicly named Mrs SOLOMON at 14:45 which was just at the right moment to be viewing the Mercury event according to the software. Of course it way day time so nobody actually saw the event.
This shot below shows the exact moment that mercury rose above the horizon as viewed from New York and only New York. It rose at precisely 9:11 and 52 seconds as viewed from Central Park. It set at precisely 19:33 and 51 seconds. Note that Neptune rose with Mercury.

This next shot below shows the moment mercury was at its optimum viewing point according o the starrynight software. The time is 1422 and Mercury is at its furthest elongation from the Sun as viewed from Earth.
The other major event was the full moon which rose at 18:14, 14 minutes after the sun set at exactly six o'clock.Other points of note are.
Uranus and thus it's moon Oberon were in Aquarius that day and all that month.
Saturn rose just below Leo the sphinx.
The Moon was in Cancer
Mars was between the horns of Taurus.
