Infact, records show that auroras continued to appear on a regular basis evenduring the Maunder Minimum, Pesnell said.

事实上，记录显示极光按一定规律持续出现，即便在蒙德极小期时也是如此，佩斯内尔说。

A crazy sun flare led to auroras visible as far south as New Mexico. This one, captured by Randy Halverson, is from Cross Plains, Wisconsin.

一道炫目的太阳耀光产生了可见极光，南至新墨西哥。这张照片由兰迪霍尔沃森拍摄，地点位于威斯康星州的交叉平原

Auroras typically are visible only near Earth's Poles, where magnetic field lines channel charged particles toward the planet.

极光通常只有在靠近地球的南北极才是可见的，在那里磁力线的通道使向着地球的粒子带电。

Intense solar activity causes disruptions of the belts, linked in turn with such phenomena as auroras and magnetic storms.

强烈的太阳活动引起范艾伦辐射带破裂，而这种破裂又和极光和磁暴等现象有关。

Goddard tried to relate the dramatic red auroras to a CME on the Sun, which was nonexistent in the SOHO images.

戈达德试图将戏剧性的红色极光与太阳的日冕物质抛射联系起来，而后者在SOHO图像上根本不存在。

Auroras glow in different colors based on the types of atoms in the atmosphere and how high they are in the sky.

极光显现不同的颜色取决于大气原子的类型和其在天空中的高度。

Magnetic field, auroras, magnetic declination and magnetic field reversals .
