Photon mean free paths, scattering, and ever-increasing telescope resolution

Philip Judge, Lucia Kleint, Han Uitenbroek +3

We revisit an old question: what are the effects of observing stratified atmospheres on scales below a photon mean free path? The mean free path of photons emerging from the solar…

On the Origin of a Sunquake during the 29 March 2014 X1 Flare

Philip G. Judge, Lucia Kleint, Alina Donea +2

Helioseismic data from the HMI instrument have revealed a sunquake associated with the X1 flare SOL2014-03-29T17:48 in active region NOAA 12017. We try to discover if acoustic-like…

A Flare Observed in Coronal, Transition Region and Helium I 10830 Å Emissions

Zhicheng Zeng, Jiong Qiu, Wenda Cao +1

On June 17, 2012, we observed the evolution of a C-class flare associated with the eruption of a filament near a large sunspot in the active region NOAA 11504. We obtained high spa…

Detection of supersonic downflows and associated heating events in the transition region above sunspots

L. Kleint, P. Antolin, H. Tian +18

IRIS data allow us to study the solar transition region (TR) with an unprecedented spatial resolution of 0.33 arcsec. On 2013 August 30, we observed bursts of high Doppler shifts s…

The solar chromosphere observed at 1 Hz and 0."2 resolution

Isabel Lipartito, Philip Judge, Kevin Reardon +1

We recently reported extremely rapid changes in chromospheric fine structure observed using the IBIS instrument in the red wing of H alpha. Here, we examine data obtained during th…
