A total solar eclipse will take place today, 2019-07-02. Totality will be visible only in the southern hemisphere, on a path seemingly crafted to avoid land as much as possible. Totality will touch down in the southwest Pacific Ocean, pass over Pitcairn Island, then finally touch land, crossing Chile and Argentina. Totality will begin at 18:03 UTC and end at 20:42 UTC.
The Exploratorium is planning a live Webcast of the eclipse from Chile, originating from the Cerro Tololo Observatory, which totality happens to cross. The Webcast will last for one hour, beginning at 20:00 UTC. Occurring in early July, near the time of Earth’s aphelion, with the Moon around two days from perigee, this will be a fairly long eclipse, with four minutes and 32.8 seconds of totality at maximum eclipse in the mid-Pacific....

In May, 1900, British magician Nevil Maskelyne, Jr., travelled to North Carolina in the United States to observe and attempt to photograph the total eclipse of the Sun on May 28th of that year. Maskelyne was the son of John Nevil Maskelyne, a celebrated magician who was also the inventor of the pay toilet. (Neither should be confused with the unrelated Rev. Dr Nevil Maskelyne, the fifth British Astronomer Royal from 1765 to 1811.) Solar eclipses had been photographed before, with the first completely successful photograph taken of the eclipse of 1851-07-28, but Maskelyne wanted to take the next step and make a motion picture of the eclipse. He used a camera with a telescopic adapter developed by his father, which he had previously attempted to use to photograph the eclipse of 1898-01-22, but his film was stolen during the return to Britain so we’ll never know what it contained.
The film from the 1900 eclipse was stunning. I have photographed four total solar eclipses (1999, 2001, 2008, and 2010), and even with modern equipment, dealing with the rapid and dramatic changes in light level in the seconds before and after totality is very challenging. However Maskelyne managed to do it (nothing is known about his equipment or technique), the result was a total success, which was shown in British theatres. The film disappeared shortly after its theatrical presentation and was believed to have been lost for over a century. In 2018, a copy (it is unknown whether this was the original or a print) was found in the archives of the Royal Astronomical Society, whose curator did not know what it was, and upon consultation with the British Film Institute’s (BFI) curator of silent films, it was identified as the Maskelyne eclipse film. The BFI’s conservators re-photographed the original celluloid film onto 35 millimetre film, which was then digitally scanned and restored as a 4K video. Here is the restored film. It is embedded here as a smaller video: click on “Watch on YouTube” to watch in full resolution.... [Read More]
