propagation in the inner heliosphere? • High cadence white light imaging in low corona (1.15 – 4 Rs) for CME acceleration • Wide angle heliospheric imagers to track CME/CIR interactions in heliosphere • Polarization information for accurate trajectory • Off-Sun-Earth line location for tracking

and bright for much of the day, although some high level cloud at times. Some patchy light rain possible by evening with lowering cloud. Chance of cloud-free hill tops above 600m: 90% or more becoming 60% in the evening. Low cloud and visibility: Generally no significant low cloud, but could form around

have had polarizers since the days of C/P on SMM and SOLWIND on P78-1. – This capability has tended to be underused. Mainly because of low cadence. Polarization at Large Elongations. ● ● High degree of polarization of Thomson-scattered light to well past 90°. Current imagers are not noise-limited

. Orange and red shading represent values above the 80th (Warm) and 90th (Hot) percentile, respectively; regions shaded in light and dark blue indicate values below the 20th (Cool) and 10th (Cold) percentile, with respect to the 1981-2010 climatology. The data used in this map are from the NOAA

. Central and eastern areas started sunny on the 11th, with more cloud elsewhere and blustery showery rain pushing into the west. After a sunny start in central areas on the 12th, most areas were cloudy, with patchy rain in some southern areas, and rain into the north later. The 13th was cloudy with light
