Abstract A brief review is presented of hydromagnetic phenomena measured by spacecraft and ground instruments at geomagnetic latitudes which connect through the dayside magnetopause. Impulsive magnetic events, proposed to be ionosphere signatures of sporadic dayside reconnection (flux transfer events), are shown to have accompanying optical and electrical signatures in the ionosphere. A direct coincidence between spacecraft-observed flux transfer events and ionosphere-based magnetic impulses has not as yet been found. Similar frequency wave-like magnetic variations have been observed between high and low altitude spacecraft and ground stations situated along the same flux tubes. These frequencies can correspond to the fundamental mode of a standing wave along a magnetopause field line.
