The Sky Tonight Update: September Equinox

The September equinox occurs at 13:31 UTC (7:30am Central time). The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world.

As the September equinox rolls by, the chances to see the aurora borealis display increases for those located at high Northern Hemisphere latitudes. According to NASA, the equinoxes are prime time for Northern Lights – geomagnetic activities are twice more likely to take place in the spring and fall time, than in the summer or winter.

The equinox may be taken to mark the end of summer and the beginning of autumn in the Northern Hemisphere, while marking the end of winter and the start of spring in the Southern Hemisphere.
