1843 5 Feb | Great March Comet or Great Comet of 1843 was first "discovered". It passed closest to Earth on March 6, 1843, and was at its greatest brilliance the following day. When at its greatest brilliance, it was visible only from southern latitudes. For a few hours on February 28, it outshone any comet seen in the previous seven centuries. The tail of the comet holds the record for actual extent. It is estimated to have stretched 300 million kilometres (or 2 astronomical units). It was last observed on April 19, 1843. At that time this comet had passed closer to the Sun than any other known object. [Great Comet in History; Notes from Baha'i History; Academic; Wikipedia; Thief in the Night p193-196]
Another comet seemed to reappear at significant times in history. The first recorded sighting for the comet that came to be known as Biela's Comet was made in 1772 with a second appearance in 1805. In 1826 Wilhelm von Biela and others contributed to work to determine that it was indeed the same comet making reappearances in elliptical orbit with an orbital period of 6.6 years. In the 1845-1846 appearance astronomers were surprised to see that the comet had split into two pieces. By 1852 only one nucleus remained visible. The 1859 apparition was very unfavourable but that of 1865-1866 was more visible. Astronomers believed that the comet had broken up and accounted for an unusual number of meteor showers. At the comet's next return in 1872 a major meteor storm occurred on the 27th of November with hourly rates of 3,000 per hour. Intense meteor displays were also noted in 1885 (15,000/hr), and 1892 (6,000/hr). [Cometography; Thief in the Night p195-196; Release the Sun p217-219] |
