Is it safe to look at a solar eclipse?
Jasmine' China Adventure Tours - Eclipse Tour FAQYes, provided you follow a few simple rules. It is not safe to look at the unfiltered surface of the sun at any time. Even when 99% of the sun is covered by the moon, it is still too bright to safely look at without the right kind of filter. We will be providing filter “glasses” for those who want to experience the “naked” eye view of the partial phases of the eclipse.
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 QuestionsQuestion: At solar eclipse, can the "Hilal" be seen?
FREQUENTLY ASKED QUESTIONS ON MOON-SIGHTINGAnswer: Solar eclipse always occurs when the moon is "New Moon" or "Invisible Moon". It occurs when the sun, the moon and Earth come in the same line. At that moment moon comes in front of the sun as seen from earth. This moon is totally invisible, because the moon does not have any light. It only reflects sun's light when it is not in line with the sun. This moon is not "hilal" and cannot be seen from any where in the world.
Related QuestionsQuestion: Is it possible to have Hilal any where in the world on the day of solar eclipse?
FREQUENTLY ASKED QUESTIONS ON MOON-SIGHTINGAnswer: When you think of a day (like solar eclipse day), that day could be 36 hours long day. Surprised?! It is true, but you have to really be patient to understand that. Solar eclipse is usually reported on a date with time in GMT.

My impression is that there will not be any total SOLAR eclipses visible from North America for a good many years. On August 21, 2017 there will be one whose track goes from Washingtion state, and exits on the east coast near the Carolinas. There will, however, be lots of LUNAR eclipses to entertain us!

Imagination Solar: frequently asked questions about solar ho...Extremely safe. The ISL systems has a safety cut out which will operate when the hot water cylinder reaches 80 degrees centigrade or 65C according to your preference. If PV powered then there is no risk of mains electrocution. Pressures are much lower than in fully filled sealed systems. We strongly recommend fitting a mixing valve to the hot water supply, to eliminate the risk of scalding in sunny weather unless you have a controller limited to 65C.
Related QuestionsTypically, how big a temperature drop do you get during a total solar eclipse?
NASA - Eclipse 99 - Frequently Asked QuestionsMy guess would be that it would be equal to the typical daytime minus nighttime temperature difference at that time of the year and location on the Earth. It would be modified a bit by the fact that it only lasts a few minutes, which means the environment would not have had much time to thermally respond to its lowest temperature, so it would probably only be 3/4 or 1/2 the maximum day-night temperature difference.

Frequently Asked QuestionsYes. Solar cells are mostly silicon, the primary component of sand. There is no exhaust and no toxic materials to leak out of the system. The electricity coming through the inverter is just like the electricity coming from household wall sockets; you should use the same care you would with utility power. All components are approved for utility interconnection and are installed according to standard construction practices.

ADEQUATE.com Lazer Tag Reference Guide: FAQAbsolutely! They actually aren't laser beams at all, they're infra-red signals that are very similar to your TV remote. In fact, some programmable remotes can learn the IR signal from a Lazer Tag gun and be used to shoot the sensors. For this reason, don't let anyone bring a remote control to your Lazer Tag games. It's cheating.
Related QuestionsHow and where in the solar neighborhood should one look for other life-sustaining planets?
Origins: FAQWe must conduct an extensive census of mature systems to determine the orbital characteristics and gross physical properties of extrasolar planets. In particular, we need to make a complete inventory of all nearby stars to find all Jovian-mass planets, and as many Neptune-like (ice-rock) planets as possible. This will require radial velocity precision of 1 m/s or better, astrometric precision of 50 microarcseconds, and the ability to image planets a few tenths of an arcsecond from a star.

Public Utilities - City of Rocky Mount, North CarolinaWhen the power supply contract was negotiated NCEMPA evaluated various alternatives, but only focused on those that were the most cost-effective. Solar and wind are still much higher costs than our contract. Until 2017 (the expiration of the contract with PEC), we are obligated to purchase all our needs from PEC. This contract is very competitive and lower than any other alternatives considered.

How are safe exposure levels to solar radiation calculated?
Solar Observing FAQDr. B. Ralph Chou laid out this method in Sky & Telescope, February 1998, p.36-40, which is recast in the FAQ maintainer's own words: The damage levels for each wavelength of light are well known. This allows the ‘safe level’ to be calculated for a filter, using as a starting point the ratio between the maximum solar intensity and the damage threshold. Just to be extra safe the maximum allowable transmittance is then set to between 1% and 0.1% of this ratio.
