澳大利亚部分地区周五晚将有机会目睹南极光奇观1。塔斯马尼亚州、维多利亚州南部和新南威尔士州部分地区预计会出现这一天文现象1。专家预报地磁指数将达到Kp 6的下限1,这为观测创造了有利但不会极其强烈的条件。
国际空间站也将在同一时段可见1。国际空间站将于周五晚7点20分在西澳大利亚州珀斯上空可见1。作为距地球400公里的轨道设施,国际空间站是除金星外夜空中最亮的物体1。
观测南极光的时机相当理想1。当前月球亮度仅为3至4%,这种低照度环境有利于南极光的观测1。南极光通常呈现绿色和红色光芒1,尽管肉眼通常难以察觉这些颜色1。
Southern Australia may witness a spectacular display of the aurora australis on Friday evening, with Tasmania, southern Victoria, and parts of New South Wales positioned to observe the phenomenon 1. The geomagnetic activity is forecast to reach the lower threshold of Kp 6, creating favorable but not exceptionally intense conditions for viewing 1.
Observers seeking the best vantage point should take advantage of the moon's low brightness at approximately 3 to 4 percent, which will enhance visibility of the natural light show 1. The aurora typically displays green and red hues, though these colors are often imperceptible to the naked eye during observation 1.
In addition to the aurora, the International Space Station will pass overhead western Australia at 7:20 p.m. Friday, becoming visible from Perth 1. Located roughly 400 kilometers above Earth, the space station ranks as the brightest object in the night sky aside from Venus 1.
