Description
We present new high-resolution spectro-polarimetric Ca II
8542 observations of umbral flashes in sunspots. At nearly
0.18", and spanning about one hour of continuous
observation, this is the most detailed dataset published
thus far. Our study involves non-LTE inversions to quantify
temperatures, mass flows and the full magnetic field vector
geometry.
