+- text: "(CNN) Skywatchers in West-Noord-Amerika zijn in voor een traktatie: een bijna vijf minuten totale maansverduistering vanmorgen. Hier is hoe het zich ontvouwt:. Het begon om 3:16 a.m. Pacific Daylight Tijd, toen de maan begon te bewegen in de schaduw van de Aarde. Voor het volgende uur en 45 minuten, die schaduw zal bewegen over de maan en verzwolgen het om 4:58 a.m. Pacific Time. De totale verduistering zal slechts vier minuten en 43 seconden duren, en NASA zegt dat maakt het de kortste van de eeuw. Kijken live op NASA TV. Terwijl mensen ten westen van de Mississippi River zal het beste uitzicht hebben, ten minste een gedeeltelijke verduistering zal zichtbaar zijn over de hele natie. Maar zonsopgang zal de show te onderbreken op de Oostkust. Delen van Zuid-Amerika, India, China en China Een maansverduistering gebeurt wanneer de zon, de aarde en de maan een rechte lijn vormen in de ruimte, met de aarde in het midden. De zon schijnt op de Aarde en creëert een schaduw. Als de maan dieper in die schaduw beweegt, lijkt het donker te worden en lijkt zelfs een roodachtige kleur te zijn. Waarom rood? Omdat de atmosfeer van de Aarde het grootste deel van het blauwe licht filtert. Sommige mensen hebben het effect van de \"bloedmaan\" bijgenaamd. NASA zegt dat maansverduisteringen meestal ten minste twee keer per jaar plaatsvinden, maar deze verduistering is de derde in een reeks van vier op een rij, bekend als een \"tetrad.\" De eerste was op 15 april 2014. De tweede was in september 2014, de volgende is zaterdag en er zal er een meer zijn, op 28 september. Als je meer wilt weten over de verduistering, NASA astronoom Mitzi Adam. Deel uw foto's met CNN iReport."
+- text: "(CNN) Filipino's worden gewaarschuwd om op wacht te staan voor flash overstromingen en aardverschuivingen als tropische storm Maysak benaderde de Aziatische eiland natie zaterdag. Slechts een paar dagen geleden, Maysak kreeg super tyfoon status dankzij zijn aanhoudende 150 km/h winden. Het heeft sindsdien verloren veel stoom als het naar het westen in de Stille Oceaan heeft gedraaid. Het is nu geclassificeerd als een tropische storm, volgens de Filipijnse nationale weerdienst, die noemt het een andere naam, Chedeng. Het heeft stabiele winden van meer dan 70 km/h (115 km/h) en gusts tot 90 km/h vanaf 17.00 uur (5 uur ET) Zaterdag. Toch, dat betekent niet dat Maysak zal geen pak een wallop. Autoriteiten nam preventieve stappen om mensen veilig te houden zoals barring outdoor activiteiten zoals zwemmen, surfen, di. Gabriel Llave, een ramp ambtenaar, vertelde PNA dat toeristen die aankomen zaterdag in en rond de kustplaats van Aurora \"zal niet worden geaccepteerd door de eigenaren van hotels, resorts, herbergen en dergelijke... en zal worden geadviseerd om terug te keren naar hun respectievelijke plaatsen.\" Aldczar Aurelio, een meteoroloog met de Filippijnse Atmosferische, Geofysische en Astronomische Diensten Administratie (PAGASA), zei dat de storm was gecentreerd 200 mijl ten zuidwesten van de provincie Aurora vanaf 5 uur (5 uur ET) en richting het westen op een 12.5 mph clip. Het is verwacht dat landval zondagochtend maken op de zuidoostelijke kust van de provincie Isabela en zijn uit de Filippijnen tegen maandag. Ahead van de storm. Isabela Gov. Faustino Dry III waarschuwde zaterdag dat bewoners moet handelen als deze zal maken landfall zondagochtend op de zuidoostelijke kust van de provincie Isabela en zijn uit de Filippijnen voor maandag."
