As for the chromosphere
, it has been viewed as the site of proton and hydrogen recapture [25-27].
We have been looking for erupting twisted solar flux ropes in the chromosphere
, but observations of these eruptions under excellent conditions are very rare," Wang said, adding that the NST images they captured provide unprecedented detail, as well as powerful new clues about their initiation and their relationship to solar eruptions and coronal mass ejections.
IRIS observations show high energy particles generated by individual nanoflare events impacting the chromosphere
for the first time.
IRIS studies the layer of the sun's atmosphere called the chromosphere
that is key to regulating the flow of energy and material as they travel from the sun's surface out into space.
These were both spectacular (see pictures) but the corona, chromosphere
and prominences were lost.
Sunrise was launched from Kiruna in the north of Sweden and, after five days drifting over the Atlantic, it landed on the remote Boothia Peninsula in northern Canada, gathering information about the chromosphere
throughout its journey.
Triplet benzophenone chromosphere
can abstract hydrogen atom from weak C-H bond or other hydrogen donor to form a ketyl radical and can be readily quenched by oxygen .
is usually invisible due to how the Sun's first atmospheric layer, the photosphere, brightness.
IRIS will fill a crucial gap in the ability of scientists to advance Sun-Earth connection studies by tracing the flow of energy and plasma through a dynamic interface region - the chromosphere
and transition region - between the solar surface and the solar corona.
and several prominences were visible at the start and end of totality.
The Interface Region Imaging Spectrograph (IRIS) mission opens a window of discovery into this crucial region by tracing the flow of energy and plasma through the chromosphere
and transition region into the corona using spectrometry and imaging.
During a solar eclipse, the flash spectrum associated with the chromosphere
of the Sun becomes readily visible [2-5].
It will obtain ultraviolet spectra and high resolution images focused on the chromosphere
and the transition region to the outer corona.
Even stranger, there is a temperature minimum of about 4000A*C between the two layers, just a few hundred kilometres above the visible surface in the part of Sun's atmosphere called the chromosphere
The book begins with the composition of our star and an explanation of the various features to be found in the chromosphere
