What happens more often, solar or lunar eclipses?
NASA - Eclipse 99 - Frequently Asked QuestionsAccording to Fred Whipple's book 'Earth, Moon and Planets', page 102-104, Solar eclipses are fairly numerous, about 2 - 5 per year, but the area on the ground covered by totality is only a few miles wide. In any given location on Earth, a total eclipse happens only once every 360 years. Eclipses of the Moon by the Earth's shadow are actually less numerous than solar eclipses; however, each eclipse covers about 1/2 the surface of the Earth.
Related QuestionsDo lunar and solar eclipses have any noticeable effect on humans?
NASA - Eclipse 99 - Frequently Asked QuestionsThere is no evidence that eclipses have any physical effect on humans. However, eclipses have always been capable of producing profound psychological effects. For millenia, solar eclipses have been interpreted as portents of doom by virtually every known civilization. These have stimulated responses that run the gamut from human sacrifices to feelings of awe and bewilderment.
Related QuestionsQuestion: How often the eclipses occur in one solar year?
FREQUENTLY ASKED QUESTIONS ON MOON-SIGHTINGAnswer: Within a given solar year, a maximum of seven eclipses can occur, either four solar and three lunar or five solar and two lunar. Question: What are the dates of all solar/lunar eclipses that occurred during Ramadan between 1840-1900 CE, to understand the claim of Qadianis (Ahmadiyya) about Mehdi.
Related QuestionsDo lunar eclipses only happen at the descending node of the lunar orbit?
NASA - Eclipse 99 - Frequently Asked QuestionsI have not thought about this very much, but there are in principle two locations where eclipses can occur. These are the points in the lunar orbit that intersect the ecliptic plane where the sun moves in the sky. These are called the Ascending Node and the Descending Node. The Ascending Node is the one located opposite of the Earth from the Sun and it is here that lunar eclipses occur. The Descending Node is between the Sun and the Earth and it is here that solar eclipses can occur.
Related QuestionsWhen were solar eclipses first predicted accurately?
NASA - Eclipse 99 - Frequently Asked QuestionsThe Babylonians knew how to predict lunar eclipses with high accuracy, but solar eclipses are far more difficult because the 'footprint' on the earth is only a few tens of miles across and requires arc minute positional accuracy and forecasting for any specific locale. Apparently Thales ca 610 BC is credited with predicting a solar eclipse using knowledge of a previous eclipse 47 years before and adding the Saros cycle. He predicted the year, but not the month and the day.
Related QuestionsWhat is a lunar eclipse? What is a solar eclipse?
The Moon | Scholastic.comAnytime there are three bodies (the sun, the moon, or planet) lined up so that one blocks the light from another, we call that an eclipse. During a solar eclipse, our moon moves between us (on Earth) and the sun and blocks the sunlight. During a lunar eclipse, Earth blocks the sun's light that normally lights up the moon. Since we are standing on Earth, what we see is that the moon gets dark. Other kinds of eclipses happen too.
Related QuestionsDO I EVER NEED TO ADJUST THE LUNAR OR SOLAR TIMES?

If you fish or hunt within a few degrees of any of these, there is no need to adjust anything. If, however, you are on the far edge of your time zone, the times could be as much as 30 minutes off.
Related QuestionsHow well are the ground tracks for solar eclipses known in advance of the event?
NASA - Eclipse 99 - Frequently Asked QuestionsI am not an expert in this area, but the positions of the Sun and Moon are known to better than 1 arc second accuracy. This means that on the Earth, the location of the track of totality is probably known to about (1.0/206265.0) x 2 x pi x 6400 km = 0.19 kilometers or a few hundred meters at the Earth's equator.

How often do eclipses happen?
Jasmine' China Adventure Tours - Eclipse Tour FAQSolar eclipses occur every year, though they are not always total. Total eclipses can be expected about every year and a half, on the average, but they can only be seen from a narrow path, so if you want to see one, you usually have to travel. The next total eclipse after this one will be on July 22, 2009, also in China. (That eclipse will be visible from Shanghai and most of the Yangtze River Valley, and Jasmine will be leading another tour to see that one, too.

FAQsIn addition to the manufacturer's warranty (which is normally 25 years for solar panels), we have relationships with solar technicians who can inspect and repair any problems that occur. Since the house will likely be grid-connected, you will not lose power should any malfunctions occur. Note, however, that the solar panels themselves are very durable and have no moving parts. Depending on your roofing materials, they will likely outlive the roofs they are installed on.

Related QuestionsHow does the Lunar PIXImus II densitometer work?
PIXImus Frequently Asked QuestionsPIXImus II utilizes Dual Energy X-ray Absorptiometry (DEXA) technology. A small x-ray source exposes the entire animal to a cone shaped beam of both high and low energy x-rays. A high-resolution digital picture (0.18x0.18mm) is taken of an image of the x-rays hitting a luminescent panel. The ratio of attenuation of the high and low energies allows the PIXImus to separate bone from tissue and, from within the tissue samples, the lean and fat.
