Marylanders will get a partial view of the total 日食 4月8日 when the moon completely blocks the face of the sun, plunging parts of the country into darkness.
关于 31 million Americans across 31 states will be in the “path of totality,” meaning they will have the most direct view of the eclipse. While Maryland is not among the states in the path, residents will see 89.7% of the sun covered during the maximum view at around 3:20 p.m.
安全
People who want to view the 日食 must look through eclipse的眼镜 to avoid eye damage from staring directly at the sun, 根据NASA.
Free eclipse的眼镜 are available for pick up at the Rockville Memorial library starting at 4 p.m. Wednesday as long as supplies last, at Damascus Library Thursday at 6:30 p.m. and during the eclipse at 2:45 p.m. 朗科图书馆.
Eclipse glasses are thousands of times darker than regular sunglasses, which are not safe to use while looking at the sun. It’s also important to avoid looking at the sun through a camera lens, telescope or binoculars while wearing eclipse的眼镜 because the concentrated solar rays will burn through the filter and can cause injury.
While the number of people who suffered eye problems after the 2017 日食 was few, a survey from The Ohio State University Wexner Medical Center found nearly 30% of Americans are unaware that looking at a 日食 without adequate protection can cause permanent eye damage.
4月’s Eclipse Compared to the 2017 Eclipse
Unlike the 2017 日食, this year’s path of totality is wider and will pass over more densely populated areas. 在31日.6 million people live in the path of totality this year compared to 12 million in 2017, 根据NASA.
While eclipse time varies by location, 2017’s eclipse saw a maximum eclipse time of 2 minutes and 42 seconds. 4月’s eclipse is predicted to have up to 4 minutes and 28 seconds of totality. During this time, the sky will darken as if it were dawn or dusk.
The sun’s magnetic field flips about every 11 years and causes a cycle of increasing then decreasing solar activity, 根据NASA. The 2017 日食 happened during a solar minimum, which meant fewer solar flares and coronal mass ejections from the sun. But this year’s eclipse will be near solar maximum. Viewers will have a better change of seeing prominences, or bright, pink curls coming off the sun.
