Recent studies, using CLUSTER ion composition data, have shown that during disturbed times, O+ beams of ionospheric origin can populate the lobes. These ~ 1 keV O+ beams are tailward moving and can originate as ionospheric outflow from the dayside cusp. In addition, recent observations from the CLUSTER mission have shown that during geomagnetically disturbed times, the O+ number density in the plasma sheet close to the reconnection X-line in the Earth's magnetotail can become comparable to, or even higher than, the corresponding H+ number density with the O+ ions carrying most of the particle pressure. We will show observations that indicate that these lobe O+ beams, as they convect towards the plasma sheet, feed the reconnection site, couple in the reconnection system and get accelerated becoming part of the source for the storm time ring current. We will compare cases under different magnetospheric conditions.
