There are times when the field is northward and there are strong flows in the dayside polar ionosphere.
在磁场方向为北的情况下，电离层白昼侧的极地地区也有很强的能量传递。
Sometimes, they happen to see the orbits of exoplanets edge-on. In those cases, the planet alternately shows more of its dayside and then more of its nightside as it circles its star.
有时，天文学家们碰巧从侧面观察到系外行星的轨道，在这种情况下，行星在围绕恒星旋转的时候就会交替地呈现出有时光面较多、有时暗面较多。
Io's dayside was deliberately overexposed in this picture to image the faint plumes, and the long exposure also provided an excellent view of Io's night side, illuminated by Jupiter.

Reconnection is most efficient when the IMF has a component that is directed southward-that is, opposite to the northward direction of the earth's magnetic field at the dayside of the magnetosphere.
在磁层昼侧，若imf有南向分量，也就是和北向的地球磁场方向相反，则磁力线重连的效率最高。
The first constellations will most likely observe the inner magnetosphere and the dayside magnetopause with each cake-size craft recording the basic characteristics of the plasmas and magnetic fields.
第一个大卫星群可能用来监测磁层内层及昼侧的磁层顶，每个蛋糕般大小的小卫星都将记录各别区域内，电浆与磁场的基本数据。
