AB: Four Utah State University Plasma Impedance Probes (PIP) were part of NASA's Sequential Rocket Study of Descending Layers in the E-Region (E-Winds). The payloads were launched at 11:19 pm, 1:41 am, 2:50 am and 3:07 am on June 30 and July 1, 2003 from Wallops Island, Virginia into the nighttime D and E-regions. These instruments provided observations of electron density and electron collision frequencies along the trajectory of the rockets. The neutral winds were measured with simultaneous TMA releases. The rockets flew into nighttime intermediate layers located between 100 to 225 km in altitude. The analysis of flight data shows a considerable amount of variability in these layers over a relativity small temporal and spatial scales. This paper presents a overview of these multi-point measurements of the mid latitude ionosphere in the context of the geomagnetic activity during the flights.
