Title: CODAR Ionospheric Observations during the CME Impact of JAN 22, 2012
Post by: ChrisSmolinski on January 23, 2012, 1556 UTC

On Jan 22, 2012 the CODAR signal on 4543 KHz was used to observer the effects of the CME impact on planet earth. The CODAR chirp was compressed and plotted with a 5000 km bi-static range. The location of the transmitter is 30.3830 N, 86.4327 W. The receiver is at 33.86N and 84.33W .
The processed CODAR plot was superimposed on the ACE plot to show the moment of impact and the effects on the time of arrival (or doppler) of the received CODAR chirp.
There appears to be some ripples around 0504 UTC after a period of slow rise of the height of the ionospheric layers. It is hard to tell if these effects are due to the CME or not...
