The news of the discovery of a comet was soon made known, for on
September 6 Dr. Gould, director of the Cordoba Observatory in South
America,[7] received information that a bright comet was visible in the
east before sunrise. His informant had seen it on the morning of
September 5, when it was described as being as bright as the planet
Venus. At Reus, near Tarragona, it was bright enough to be seen at one
time through a passing cloud when at a distance of only three times the
diameter of the sun from its edge, or “limb,” as it is technically
termed. According to the report of Dr. Gould regarding the weather
conditions prevailing at Cordoba, the morning of September 7 was cloudy
and the eastern sky overcast on every morning during a whole week.
Nevertheless, on one occasion it was thought that a part of the comet’s
tail could be seen. It was not until September 14 that conditions were
again favorable for observing the comet.
Fortunately the link in the chain of observations was supplied by an
enthusiastic amateur astronomer, Mr. John Tebbutt, who watched the comet
from his observatory at Windsor, New South Wales. On September 8, he
received a telegram from the Government Astronomer at Melbourne, to the
effect that a large comet was reported due east at four o’clock in the
morning. Other messages were received during the day from different
parts of the colony, and from the information thus supplied Mr. Tebbutt
was enabled to observe the comet on the mornings of September 9 and 10.
By this time the nucleus of the comet was large and remarkably
brilliant, and the tail about 3° or 4° in length, not quite the distance
separating the pointers in Ursa Major.

Mr. Tebbutt had already distinguished himself as a successful
comet-hunter, and in addition had vainly endeavored to form a society
such as existed for comet-hunting in the northern hemisphere, but his
efforts only ended in disappointment. As he wrote in his _Memoirs_,
“although several astronomers owned telescopes suitable for the work,
there was obviously a distaste for systematic observation.” He took
great pride in his miniature observatory at Windsor, actually his own
handiwork, for he was his own bricklayer, carpenter, and slater
combined. During a visit to the observatory in 1912 the writer was shown
numberless books containing the records of fifty-five observations of
the comet of 1882, extending from September 8 of that year to March 2,
1883. These observations were made by Mr. Tebbutt with his four and a
half inch equatorial, with the exception of four made with the transit
instrument in full sunlight. Moreover, Mr. Tebbutt was the first to see
the comet in full daylight with the unaided eye.
