This plot shows the current extent and position of the auroral oval in the northern hemisphere, extrapolated from measurements taken during the most recent polar pass of the NOAA POES satellite.

The red arrow in the plot, that looks like a clock hand, points toward the noon meridian.

This presentation provides an estimate of the location, extent, and intensity of aurora on a global basis. For example, the presentation gives a guide to the possibility that the aurora is located near a given location in the northern hemisphere under the conditions that existed at the time of the most recent polar satellite pass.

These images show the outer Solar atmosphere, or corona, as viewed by the GOES 12 Solar X-ray Imager (SXI). This region of the Sun has a temperature of one to several million degrees kelvin (Mega Kelvin MK) and is active on a time-scale of seconds to weeks.

Here the green image represents the ionized gas (plasma) of the corona at about 4.0 MK. Bright areas, referred to as active regions, are associated with sunspots seen in white light images and may produce explosive events known as flares. Dark regions are coronal holes where the fastest solar wind originates.
