The chromosphere processes all magneto-convective energy
that drives coronal heating
and requires a heating rate that is at least as large as
that required for the
corona. Yet many questions remain about what drives the
chromospheric dynamics and
energetics and how these are connected to the transition
region and corona. I will
review some recent results from IRIS in which...

Using high-resolution spectral and imaging data taken by the Interface Region Imaging
Spectrograph (IRIS), we investigate the transition region explosive events, which are
believed to be signatures of magnetic reconnection, observed in the solar transition
region. We found that the explosive events are closely associated with dynamics of
small-scaled loops in the solar transition region....

Since the early days of the CRisp Imaging SpectroPolarimeter (CRISP) at the Swedish
1-m Solar Telescope (SST) the Halpha wing data of more active regions display
intermittent flows at apparent chromospheric canopy heights. These flows appear to be
aligned with canopy fibrils visible at the Halpha line core, with the blobs that
constitute these flocculent flows" seemingly moving from one...

Emerging flux regions (EFRs) are known to exhibit various
local heating events in the
chromosphere. In this talk, we will introduce our two topics
on this issue utilizing
both Hinode and IRIS observations. First, we will focus on the
repeated brightenings and jet ejections seen in the light
bridge structures in EFRs
(Toriumi et al. 2015a,b).
Combining not only the Hinode-IRIS...

We report on four fan-shaped sets of high-speed jets
observed at the Swedish 1-m
Solar Telescope. These jets appear to be rooted close to
sunspots and at light-bridge
edges and to be associated with the change of sign in the
field polarity. We will
present the results of a study of their dynamics, obtained
using high-resolution
imaging spectroscopy in Hα, and the photospheric...

The solar chromosphere observed in H-alpha consists mostly of narrow fibrils. The
longest typically originate in network or plage and arch far over adjacent
internetwork. We use data from SST, IRIS and SDO to analyze one well-observed
example in a quiet area. It resulted from the earlier passage of an accelerating
disturbance in which the gas was heated to transition-region and even...
