GLASTONBURY, UNITED KINGDOM - SEPTEMBER 28: (EDITORS NOTE: Image was created as a digital composite) Two images show the moon appearing as a 'supermoon' at midnight (L) and a red-tinged 'blood moon' as an optical effect of a total lunar eclipse visible at 3.45am (R) on September 28, 2015 in Glastonbury, England. Tonight's supermoon - so called because it is the closest full moon to the Earth this year - is particularly rare as it coincides with a lunar eclipse, a combination that has not happened since 1982 and won't happen again until 2033.
