Proposal Type: General Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: Urgent Terrestrial Aeronomy Ionosphere 28.50 Hours na

Arecibo observations of E region at 600m resolution in support of the EUV Variability Experiment (EVE) mission.
ABSTRACT:
We request ISR observations of the ionosphere from 1hour or so before sunrise in the F-region to an hour or so after sunset in the F-region for one day (ASAP). The selected day needs to be coordinated with the EVE satellite team of Tom Woods, Frank et al. so that EVE is operating across its full range. The ISR mode we would be interested in is one that generates full ionospheric profiles E- through F- layer, topside. But with 1 km type resolution through the E-layer. I hope the day we pick is "quiet", although at Arecibo these really is no quiet day say. I think the main idea is that there are no ma jor solar active events or super-storms. The request is urgent because an instrument on the spacecraft is failing and may cease operations at any time.
