The Effect of Solar Flares, Coronal Mass Ejections, and Solar Wind Streams on Venus’ 5577 Angstrom Oxygen Green Line
We observed the Venusian 5577.3 Å OI nightglow emission feature after solar flares, coronal mass ejections, and solar wind streams from December 2010 to July 2012 using the high resolution Astrophysical Research Consortium Echelle Spectrograph.

The Effect of Solar Flares, Coronal Mass Ejections, and Solar Wind Streams on Venus’ 5577 Angstrom Oxygen Green Line
We find the greatest emission occurs after CMEs and suggest that particle precipitation is the main contributor to green line emission.

The Characteristics of the O-2 Herzberg Ii and Chamberlain Bands Observed with Virtis/Venus Express
Recent observations with the VIRTIS instrument on board Venus Express allowed us to re-examine the Herzberg II system of O2 and to further study its vertical distribution, in particular the (0–m00 with m00 = 7–13) bands.

Atomic Oxygen Emission Intensity Ratio: Observation and Theory
We argue that agreement among theoreticians on the numerical value of a particular physical parameter must still withstand the test of observation.

Feo Emission in the Mesosphere: Detectability, Diurnal Behavior, and Modeling
The temporal behavior of the FeO and OH emissions was compared to model results from the one-dimensional and time-resolved model FeMOD, which describes the iron chemistry in the mesosphere/lower thermosphere.

Collisional Relaxation of O(2)(X(3) Sigma(-)(G), Nu=1) and O(2)(A(1) Delta(G), Nu=1) By Atmospherically Relevant Species
Laboratory measurements are reported of the rate coefficient for collisional removal of O2(𝑋3𝛴−𝑔 , υ = 1) by O(3P), and the rate coefficients for removal of O2(a1Δg, υ = 1) by O2, CO2, and O(3P).

Discovery of the FeO orange bands in the terrestrial night airglow spectrum obtained with OSIRIS on the Odin spacecraft
An unidentified pseudo-continuum in the 600 nm region is observed in the upper mesosphere with the limb-scanning OSIRIS imaging spectrograph on-board the Odin spacecraft.

The Faraday Filter-Based Spectrometer for Observing Sodium Nightglow and Studying Atomic and Molecular Oxygen Associated with the Sodium Chemistry in the Mesopause Region
This paper describes the operational principles, design and field testing of a new, compact, Faraday filter-based spectrometer to measure the D2 (589.158 nm) to D1 (589.756 nm) intensity ratio of the sodium nightglow.

Study of the Image Quality and Stray Light in the Critical Design Phase of the Compact Echelle Spectrograph for Aeronomical Research (CESAR)
The success of the high resolution nightglow studies conducted with the Keck telescopes on Mauna Kea and the Very Large Telescopes in Chile led to the design of the Compact Echelle Spectrograph for Aeronomical Research (CESAR).

Chemical Origins of the Mars Ultraviolet Dayglow
Airglow optical emissions from planetary atmospheres provide remotely observable signatures of atmospheric composition, energy deposition processes, and the resulting chemical reactions.

Visible and Near-Infrared Nightglow of Molecular Oxygen in the Atmosphere of Venus
We search for the emission of the Herzberg II system of O2 at 400 nm–700 nm in spectra obtained with the VIRTIS instrument on Venus Express.

The 557.7 Nm Oxygen Green Line in the Venus Nightglow
In this presentation we consider the argument for a mesospheric vs an ionospheric source.
