Explore the Total Solar Eclipse By Claire Raftery Explore our 2017 eclipse map. Passing through 12 states, this eclipse is the first total solar eclipse to cross the United States from coast-to-coast since 1918. The last total solar eclipse in the U.S. was in 1979. For a few minutes, millions of observers will gather along a narrow band to witness the same event making it a perfect opportunity to become a citizen scientist. While simply witnessing a total solar eclipse is fascinating and moving, some people are taking the opportunity to do some citizen science during this event – and you can too! For beginners or parents with children, the great news is that you can still collect meaningful data by making some basic observations. All you’ll need is a notebook, pencil an observant attitude. Become a scientist! Note changes in how the wind blows. Or changes in temperature. Notice how birds and animals act as totality approaches. In the minute or so before totality when Bailey’s Beads, formed from sunlight streaming through the deepest valleys on the Moon, look around for bands of shadows. Note shadow direction and general speed. Look under trees as the leaves cast crescent shadows as the eclipse progresses. Or use the voice recording feature on your smartphone to capture other witness’ experiences and thoughts. Some basic citizen science projects include: - Smartphone photography: Join in the millions of people who will be capturing photos of eclipse with their smart phones. With a little preparation, you can capture some stunning images.

All you need for this activity is a thermometer or digital weather station. Many mobile apps don’t use the temperature at your location but rather a city or weather station nearby. For more accurate readings with your phone, find an app that uses an external temperature sensor. - Dimming of daylight: This simple observation will show you how the darkness during totality compares with daytime, dusk and twilight. Use a light meter to measure the change in brightness or simply record your observations in a notebook. - Ambient Sounds: Record the changing sounds of the environment around you during the eclipse. You can send them to eclipsesoundscapes.org to benefit sociologists, birders as well as the blind and visually impaired. More formal citizen science projects include the Citizen CATE Experiment, which stands for Continental-America Telescope Eclipse. The experiment will use a network of more than 68 telescopes equipped with identical telescopes and digital cameras spread along the path of totality, each a few hundred km from each other, beginning in Oregon and going all the way to South Carolina. With each site only observing approximately 2.5 minutes of totality, as the shadow passes over the horizon, the next observing site is ready to begin observing. The goal of this eclipse relay race project is to produce a scientifically unique dataset of high-resolution, rapid-cadence, white-light images focusing on the inner solar corona. This part of the Sun’s atmosphere is incredibly challenging to image. With 90 minutes of continuous observation, scientists hope to gain important insights about the dynamics of this area of the Sun, including how the solar wind is accelerated.

Sunglasses don’t cut it! Only during totality, when the Moon completely blocks the Sun, is it safe and desirable to remove your eclipse glasses and enjoy one of the only ways to see the solar corona, the Sun’s wispy outer atmosphere.

आज सूर्य ग्रहण लाग्ने काठमाडौं । आज खण्डग्रास सूर्य ग्रहण लाग्दैछ । तर यो सूर्यग्रहण नेपालको कुनैपनि हिस्साबाट नदेखिने नेपाल पञ्चांग निर्णायक समितिका सचिव सूर्यप्रसाद ढुंगेलले जानकारी दिए । नेपालमा सूर्यग्रहण नदेखिने भएकोले यसलाई बार्नुपर्ने उनले बताए । उनका अनुसार नेपाली समय अनुसार दिउँसो १ बजेर ५७ मिनेटदेखि साँझ ६ बजेर ५६ मिनेटसम्म लाग्ने यो ग्रहण लाग्ने छ । यो ग्रहण सुदूरपूर्वी एवं उत्तर अमेरिका, मगोलिया, चीन, नर्वे, ग्रीनल्याण्ड, युके, युरोप र प्यासिफिक क्षेत्रबाट देखिने छ । जेठ महिनाको अमावश्यमा हुन लागेको सूर्यग्रहण यो वर्षको पहिलो सूर्यग्रहण हो । ग्रहणको समयमा सूर्यमा कुण्डलाकार आकृति देखिनेछ । जसलाई पश्चिमाहरुले रिङ अफ फायर भन्ने गर्छन् । सूर्य, चन्द्रमा र पृथ्वी सीधा रेखामा आउँदा कुण्डलाकार सौर्यग्रहण लाग्छ । हामीलाई तपाईंहरूको सल्लाह र सुझाव दिनुहोला जसले गर्दा हामीले यो विकास पत्रकारिता, लेखन र साहित्यको क्षेत्रमा अझ राम्रो गर्न सकौं । यहाँहरूका लेख तथा रचनाहरु छन् भने पनि हामीलाई पठाउनुहोला । छापिन योग्य रचनाहरू हामी छाप्ने छौं ।सम्पर्क इमेल : sendyourarticle@samayasamachar.com
