Tonight's Sky for April 2: Weekend Aurora Alert


NOAA is forecasting a 60% chance of geomagnetic activity tonight and into tomorrow morning as the Earth will be entering a co-rotating interaction region (CIR), which is a fancy way of saying that the Earth will be transitioning from being in a fast to slow stream of the solar wind. Such transition zones are often good for sparking displays of aurora, also known as the Northern Lights.
