| Observation Instruments | Near InfraRed Aurora and airglow Spectrograph-2 (NIRAS-2): A wide field imaging spectrograph with two volume phase holographic gratings and three slits, designed for the wavelength range from 1.05 to 1.35 um in which sky background intensity is weaker than in visible subrange. |
| Sample Data |
A 2-D imaging spectrogram obtained by the NIRAS-2 with 30-sec integration time.

| Publication method | You can download metastable helium airglow brightness data obtained by the NIRAS-2 observation at https://polaris.nipr.ac.jp/~niras/index.html#!data.md In addition to the helium airglow emission, we also have spectral data of OH Meinel band system ((4,1), (5,2), (6,3), (7,4), and (8,5) bands), O2 atmospheric band at 1.27 microns, and auroral emissions in N2+ Meinel band and N2 1st Positive band. If you have interests in such spectral data mentioned above, they can be provided based on a collaborative study. Please contact the Principal Investigator. |
