In support of the January 28 to February 11, 2005 HAARP experiment campaign, plasmaspheric He+ pseudo-density has been obtained from the IMAGE EUV instrument. Average He+ density and the standard deviation of the average are obtained for a range of L-shells within 0.15 and a range of MLT within 0.25 hours of the HAARP location as projected in dipolar coordinates. He+ pseudo-density is described in the Appendix of our Notches paper, currently in review with JGR.

The He+ pseudo-densities derived for each day can be viewed by clicking on the corresponding day below. As new telemetry becomes available, the files referenced in these links will be updated.
