日全食的路径: 在线博彩 professor discusses what to expect in San Antonio

天文学的影响
在线博彩 researchers, staff 和 students commemorate rare total solar eclipse

2024年2月27日 San Antonio was last cloaked in the moon’s shadow during a total solar eclipse in 1397. It’s a once-in-a-lifetime celestial event that everyone must witness, according to 安吉拉斑点, professor 和 chair of the 在线博彩物理和天文学系. 

周一, 4月8日, people from around the world will gather again to experience this historic phenomenon, 因为月球慢慢地位于地球和太阳之间, 为阿拉莫市带来了另一次日全食. 

“It’s hard to convey just how amazing it is to experience an eclipse,” Speck said. “它看起来很漂亮, but you also feel it on your skin because it cools down 和 you get a breeze. 对我来说,不只是一件事. You have all this stuff going on all at once, 和 you have a very limited time to take everything in. 也有野生动物的声音取决于你在哪里.”

Location is everything when it comes to fully experiencing a total solar eclipse. 日全食的路径, 月球的影子完全挡住了太阳的地方, 一条狭长的陆地大约有100英里宽吗. 几个大城市都坐落在这个令人垂涎的地理位置上, 包括圣安东尼奥和波恩, only a small portion of the Earth’s surface will truly witness the historic moment.


“你要么100%处于日全食的轨道上,要么不是. At 99%, there will be so much sunlight flooding through, it’ll be like an overcast day. It’s an entirely different experience to be in the path of totality.”

“圣安东尼奥市中心不会完全黑暗,”斯派克解释说. “你要么100%处于日全食的轨道上,要么不是. At 99%, there will be so much sunlight flooding through, it’ll be like an overcast day. It’s an entirely different experience to be in the path of totality. 你必须尽可能地靠近中心.”

The 在线博彩 Main Campus will be on the inner edge of the path of totality. Those on campus will catch the totality of the eclipse for 2½ minutes, from 1:33 p.m. 到下午1:35.m. Boerne viewers will get over three minutes, compared to a mere 21 seconds that viewers near Nelson W. 沃尔夫体育场将见证这一切.

整个日食从12:14分开始.m. 第一次接触时,月球与太阳的边缘相遇. As the moon slowly glides over the sun, Speck urges viewers not to stare without proper protection. Eclipse glasses are critical to ensure viewers witness the progression of the eclipse.

Another method to witness the eclipse safely, 和 favored by Speck, is using a disco ball. Each square metallic pattern captures the shape of light from the sun, 在地面上反射出新月的图案.

在日食期间,温度下降. Birds flock throughout the darkening sky as they settle into silence 和 get ready to sleep. 在全食前的最后一刻, the moon blocks enough of the sun’s rays to reveal the faint solar corona.

Unlike daily sunsets that bestow a colorful sky reserved to one portion of the horizon, a mosaic of colors will engulf the whole horizon in the seconds leading up to totality.

“There’s a huge difference just before 和 once in totality,” Speck said. “快看,不然你会错过的.”


进一步探索

Once the moon has completely covered the sun, reaching totality at 1:33 p.m. 到下午1:35.m.在美国,不戴日食眼镜观看日食是安全的.

“它会像满月一样明亮,”斯派克说.

The entire progression of the eclipse will end in San Antonio at 2:55 p.m.

April’s event is the last chance to catch a total solar eclipse from the contiguous United States until 2044. 2033年,日全食将席卷阿拉斯加西部.
