| The extracted pixels from raw images have been plotted over a full day of imaging from AGO P1 and South Pole station, creating latitude vs. time plots. Geomagnetic noon occurs around 1530 UT, consistent with the poleward contraction of the cusp. | |||||||||
| The above keogram data are sorted according to the month and each plot shows all available stations for that day. For scientific use, especially for a zoom into a shorter time period, trasformation to geographic or geomagnetic coordinates and absolute values please contact the all-sky camera PI.
