IHOP 266 - small-scale reconnection in coronal hole plumes


HOP description.

For this IHOP the intention was to use EIS in sit-and-stare mode to search for activity at the base of plumes that may be due to small-scale reconnection. Supporting data from IRIS (if available) generally is a 16-step raster. Below I list all the Cool_loop_stare observations (see Cool loop studies for more details), even if they weren't run on plumes. A further table lists EIS raster observations.

Cool_loop_stare (EIS sit-and-stare)

The table below summarizes the observations. The codes are: "EqCH" - equatorial coronal hole; "PCH" polar coronal hole; "B" - plume base; "L" - plume leg. Note that SOT filtergram observations are not available from the 19-Mar-2016 observations onwards. If SOT observed with only SP, then I put an asterisk next to Y.

EIS raster studies

Mostly these are with the EIS Cool_loop rasters (see Cool loop studies), and several are from IHOP 267.
