Dr Minjae Kim on this weekend's partial lunar eclipse/Hunter's Moon
Dr Minjae Kim, Research Fellow, Department of Physics, University of Warwick, said:
"On 28 October, observers in the UK will witness a partial lunar eclipse where a section of the Moon will be obscured by Earth's dark umbral shadow. During the partial lunar eclipse, the moment when the Moon begins its passage into Earth's umbral shadow will start at 20:35:25 BST. This phase, particularly notable for viewing, will be lasting for 1 hour and 17 minutes. The climax of this occurrence, termed the 'maximum eclipse' or 'greatest eclipse', is projected for 21:14:05 BST.
"The pinnacle magnitude of the eclipse, indicating the portion of the moon's diameter covered by the deepest region of Earth's shadow, will be 12.2%. At the same time, only a scant 6% of the moon's surface will undergo obscuration at the height of the eclipse. Given this, the visual spectacle will be relatively understated. As such, meticulous timing is paramount for those keen on capturing the event.
“For the Halloween weekend, we also have a full moon to add to the spooky atmosphere. The Hunter’s moon, sometimes known spookily as the ‘Blood’ moon, is the full moon which tends to appear in October in the Northern Hemisphere. This year, it will occur on 28 October. The Hunter’s Moon proceeds the Harvest Moon, which is the full moon closest to the autumnal equinox in late September. Its name arises from many years ago, in North America, when deer had been fattened over the summer, ready for hunting in Autumnal moonlight, to provide sustenance over the colder months.
“Combined with the partial lunar eclipse, it could provide extra eeriness for any Halloween-themed weekend events!”
