I've heard that on May 19, 1780, in the northeastern part of North America, there was a period of "extraordinary darkness," which began between 10 A.M. and 11 A.M. and lasted until the middle of the next night. Also, the full moon rose at 9 P.M. that evening but was not visible until midnight, when it had the "appearance of blood." I've checked records of solar and lunar eclipses for that date, and none was close enough to have caused the phenomenon. Do you have any information about such an event? Could you provide an explanation for it?
For a generation of New Englanders, Friday, May 19, 1780, was a date never to be forgotten. The Sun was blotted out by a strange darkness, varying in intensity and length from place to place, but extending from New Jersey and New York across Connecticut, Rhode Island, Massachusetts, and southeastern New Hampshire into Maine. For several days prior to the "Dark Day," the Sun was obscured by smoky clouds, and the Moon took on an unusual reddish color. Darkness began around 10 in the morning and lasted throughout the day. (When the Connecticut legislature proposed adjournment following the belief that the day of judgment was at hand, a Colonel Davenport declared: "I am against an adjournment. The day of judgment is either approaching, or it is not. If it is not, there is no cause for an adjournment; if it is, I choose to be found doing my duty.") The night that followed was no comfort to the fearful, being unusually black and impervious to any artificial light. The next day, a fine sulfurlike substance was noticed on the edges of water, but the only reports of adverse effects concerned the death of a number of birds. The first theories of a comet or solar eclipse were ruled out, and the earliest guesses regarding smoke from forest fires turned out to be accurate. Out-of-control forest fires, extending from New Hampshire into New York State, burned furiously for a week preceding the dark day, creating great suffocating clouds of smoke. An unusual atmospheric condition trapped the smoke until it reached sufficient density to blot out the Sun. However, for many New Englanders, the Dark Day was an inexplicable mystery, never recalled without a feeling of awe.

Air temperature is not affected by Moon phase. It is affected by the season and whether there is a cloud cover, among other things. On a clear night, heat rises from Earth if there is no cloud cover holding it in. This might make you think it's colder because there is a full Moon, but it's really colder just because the sky is clear.
During the waxing phase -- that is, when the Moon is between new and full.
Historically, the Native Americans of the northern and eastern United States kept track of the seasons by giving a distinctive name to each full Moon. With some variation, the same names were used throughout the Algonquin tribes from New England to Lake Superior. These remain the full Moon names we use today.
Well, there's quite an inventory. Of course, there's the American flag, left by the first visitor, Neil Armstrong. The first Apollo landing crew also left a commemorative plaque. The remains of seven unmanned lunar probes, Surveyors 1 through 7, are there, plus three lunar rovers. There are six long-term scientific stations on the Moon, which include seismometers to measure tremors in the Moon's crust and some reflectors to bounce back light beams that we send up there. The Russians left several unmanned probes and assorted lunar rovers on the Moon as well.
The new Moon always rises at sunrise. The full Moon always rises at sunset.
The Moon is approximately 4.6 billion years old.
When you watch the Moon move from east to west, it travels its own diameter in about 3 minutes. The speed at which we see it move is mostly due to the Earth's movement, not the Moon's. The Earth's movement accounts for 95 percent of the shifting position of the Moon. The other 5 percent is actually the Moon itself moving.
