海外TECH	Engadget	Solar Eclipse 2024: How to watch and record the total eclipse on Monday	https://www.engadget.com/solar-eclipse-2024-how-to-watch-and-record-the-total-eclipse-on-monday-163035394.html?src=rss	On April a solar eclipse will darken the skies This is a rare astronomical event The last North American total solar eclipse was on August and there won t be another on visible on the continent until The path of totality ーwhere the sun will be fully blocked by the moon ーcovers over million people in the US Canada and Mexico Those lucky folks may see the sun s corona and a diamond ring ーboth dramatic sights Other regions will experience partial eclipses with the level depending on how close you are to totality Watching the moon eat into the sun even a bit is still a spectacular sight So which cities and regions will experience totality and when What s the weather forecast in those areas And if you do have a clear view how can you safely watch and record the event Where in the US will you experience the solar eclipse totality and when The good news is that many major centers are in the mile wide band of totality so millions of people will be able to see a full solar eclipse It follows a northeast path so Mexico s Pacific coast will get the first views in Mazatlan starting at around AM PDT total eclipse starting at PDT followed by the city of Torre n all times local The total eclipse moves into the United states at PM CDT Eagle Pass Texas then hits Austin Fort Worth and Dallas ーthree out of five of the most populous Texas cities From there it moves into Little Rock Arkansas followed by select parts of Missouri Illinois and Indiana including Indianapolis NASAOhio cities Dayton Toledo and Cleveland get the full show followed by Erie Pennsylvania then Buffalo Rochester and Syracuse in New York along with Maine Canada is in on the fun too with parts of southern Ontario Hamilton Niagara Falls and Quebec Montreal getting the totality along with New Brunswick PEI and finally Bonavista Labrador at PM NDT Newfoundland Time If you re elsewhere on the continent and can t travel know that the closer you are to the band of totality the more the sun will be obscured by the moon this map shows how much of the eclipse you ll get depending where you are on the continent An impressive list of major centers are within miles of totality so they ll get a percent or better eclipse Houston St Louis Memphis Nashville Chicago Cincinnati Detroit Toronto New York Boston Anyone in the US south midwest and northeast should get a decent spectacle as will folks in Canada s southeast and Atlantic coast Even if you re not in those regions you might still see and can capture a mini eclipse How long with the solar eclipse last From the beginning when the moon first starts to cover the sun partial eclipse until the end when the two bodies part ways is a good long time up to two hours and forty minutes in Dallas and in Caribou Maine However totality itself is brief with the duration dependent on how close you are to the center of the totality band and the time of day It s at just under four minutes in Dallas less than three minutes in Presque Island Maine and a mere minute and seconds in Montreal As such you ll need to be ready and hope that the skies are clear during that brief window What s the weather forecast in my area It s still early for an accurate forecast but a week is enough to get a general idea by region Suffice to say April isn t the ideal month for clear skies That said an eclipse can still be visible through light cloud cover and even if it s thick the sky will grow dramatically dark Unfortunately the odds of precipitation are indeed above average across most of the band of the eclipse Forecasts predict that the chances for clear skies are better the farther northeast you live the opposite of historical trends To wit Dallas has showers forecast throughout the day percent which would mean continuous cloud cover and no clear view if that holds That improves a bit when you get to Indianapolis partly cloudy percent chance of rain with things better still in Buffalo New York partly cloudy percent Things are looking good right now in Montreal though with mostly sunny skies and only a percent chance of rain and the same goes for Fredericton New Brunswick Niagara Falls also figures to have decent weather during the eclipse mostly sunny percent and is in the path of totality which has led to the city declaring a state of emergency out of caution Officials estimate that a million people could pour into the area creating potentially dangerous crowds How can I watch the solar eclipse at home Staring at the sun is obviously dangerous for your vision and doing so during an eclipse can be just as harmful Even though you may not feel discomfort immediately you may damage your eyes via an affliction called solar retinopathy That can lead to serious consequences like eye pain blind spots blurred vision and more American Astronomical SocietyTo view it safely you must purchase a pair of approved solar eclipse glasses based on an international safety standard called ISO regular sunglasses won t do That dictates the maximum luminous transmittance along with the range of permissible wavelength transmittance UVA UVB and infrared There s certainly still time to grab a pair if you don t have them already The American Astronomical Society AAS has many recommendations for manufacturers and vendors both online and at retail chains Warby Parker for one is offering free glasses limit two per person while supplies last You can also find them at Staples Lowes and Walmart or online at B amp H and multiple science and astronomy stores The AAS advises against searching for the lowest price on Amazon or eBay however in case you get a bad knock off Before you buy a solar viewer or filter online we recommend that you make sure that the seller is identified on the site and the seller is listed on this page it says on its Solar Eclipse Across America site How to watch the solar eclipse safely without glassesCanadian Space AgencyIt s possible to view an eclipse without glasses via indirect means as well The simplest way is by punching a small round hole in a piece of thick paper or cardboard then positioning it so the sun shines through the hole onto the ground or a flat surface you can also attach a piece of foil with a hole as NASA shows here That will project an image of the Sun s disc letting you see the eclipse in real time The same pinhole principle would let you use anything with perforated holes like a colander projecting dozens of tiny eclipses on a surface Trees can do the same thing casting weird leaf shadows with little solar eclipse chunks out of them Benjamin Seigh WikimediaFor a bit better experience you can build a crude box projector With that the sun shines through a hole in tin foil onto a white card and you can look through a larger hole at the card with the sun behind you The Canadian Space Agency explains exactly how to make that Never ever view an eclipse directly through a pair of binoculars or a telescope as that s a guaranteed way to damage your eyes That said you can use a pair of binoculars or a telescope to project the sun onto a piece of paper as shown in this video How to take photos or video of the solar eclipseUnfortunately you can t just point your smartphone or camera at the sun to record the eclipse as the brightness will overwhelm the sensor and ruin the image and possibly damage the sensor Luckily you can shield your camera just as you do your eyes The cheapest way to do that is to buy an extra set of eclipse glasses then cut out an eyepiece from one and tape it over the smartphone or other camera lens That will reduce the light levels enough to see detail in the sun throughout the partial eclipse and totality You can also purchase dedicated smartphone solar filters like the VisiSolar Photo Filter which are designed for cameras and not direct viewing Another choice is the Solar Snap Eclipse App Kit which also offers an app that aids in photographing the eclipsed sun It s advisable to also wear solar glasses when setting up your smartphone or camera to protect your eyes If you re shooting the eclipse with a dedicated mirrorless or DSLR camera you ll need either a mylar stop ND neutral density or hydrogen alpha solar filter Again do not look directly into a DSLR s optical viewfinder at the sun if the lens doesn t have one of those filters attached the electronic viewfinder on a mirrorless camera is safe To photograph the eclipse with a smartphone turn the flash off and put the camera into ultrawide or wide mode so it stays in frame Do NOT look directly at the sun to line up your camera if you re not wearing solar eclipse glasses Don t use the digital zoom to try to make the eclipse bigger as you ll lose resolution you can zoom in later in your photo editing app Once focus is set on the sun use your smartphone s focus lock feature so that it doesn t hunt for focus and blur the eclipse During totality the diamond ring effect only lasts a split second so use the burst mode of your camera or you ll likely miss the shot And try to capture RAW rather than JPEG images to keep the maximum detail possible for later editing Some iPhone and Android smartphones have RAW capability built in if not you can use a third party app If you decide to capture video you ll need a filter as well of course But you should also use a tripod as shooting handheld will induce blur and result in a shaky video Even a cheap tripod will do the trick along with a simple smartphone holder Capture the highest resolution you can K or even K at the highest quality possible You ll also capture any cheering shouting etc ーa precious souvenir you can look back on again and again More resourcesThere are plenty of government and private sites with more information about the eclipse starting with the AAS s eclipse site detailing things like eye safety imaging resources and even a totality app ーan interactive map that shows what you ll see at any location in North America for the total solar eclipse of April NASA also offers a dedicated site for the North American Eclipse as does the National Weather Service and National Solar Observatory A private site called Great American Eclipse is largely commercial but does have a very useful map showing the band of totality and how much of the eclipse you ll see depending on location along with a comprehensive list of eclipse times and durations by city Update April PM ET This story was updated after publishing to include more details about the total solar eclipse s path of totality This article originally appeared on Engadget at	2024-04-05 16:37:40
