 Hello Halley; quite something for nearly nothing.
Royal Astronomer Edmund Halley indeed observed the comet, though when he did so in 1682, it did not bear his, or any name at all.
It was Halley who conceived that the bodies observed in 1531, 1607, and 1682, were indeed one and the same, a bright comet in an elliptical orbit with a period of approximately 76 years.
This time around the comet will pass only within 39 million miles of the earth, which is farther away than it has been on previous trips (in the year 837, it passed by at a distance of only 3.7 million miles and was for a time visible in broad daylight).

In 1758 (Halley was ondertussen overleden) was er - zoals voorspeld - inderdaad een komeet zichtbaar.

 Comet Halley
Edmund Halley was a good friend of Isaac Newton.
Tracing back in the historical records for recordings of bright comets and their positions in the sky, it was concluded that Halley had been observed periodically as far back as 240 B.C. The most recent return was in 1986, and the predicted next appearance of Halley in the inner Solar System will be in 2061.
Notice that Halley's orbit extends essentially to the distance of Pluto, but when Halley is at its greatest distance from the Sun (aphelion) it is below the plane of the ecliptic (green color) while that portion of Pluto's orbit is above the plane of the ecliptic (blue color).

 South African Museum - Halley's Comet   (Site not responding. Last check: 2007-09-17)
The notoriety of this comet arises principally from the realization in 1705 by Edmund Halley that the bright comets seen in 1531, 1607 and 1682 were one and the same object, travelling in an elongated orbit around the Sun in a period of approximately 75,5 years.
Halley’s Comet was probably first captured only a few thousand years ago and is now not as bright as formerly.
As a result, Halley’s Comet in 1986 is not expected to be as spectacular a sight as some other comets seen in recent years — for example Comet Bennet (1970) and Comet West (1976).

Edmund Halley (1656-1742) was a British Astronomer, who was the first to calculate a comet's orbit.
