These observations of Jupiter represent quick-look images of the planet made using the scientific-grade guide camera on SpeX at NASA’s IRTF.
The files are in NASA-standard FITS format with details in the headers. Observations are composites of multiple exposures, corrected for sensitivity inhomogeneities (flat-fielded), with limb-fitting and central meridian information included.
Most images were obtained by IRTF staff in brief intervals to monitor atmospheric changes at wavelengths of:
- 1.58 μm (deep-cloud reflectivity)
- 2.16 μm (upper troposphere and lower stratosphere)
- 3.42 μm (H3+ auroral emission)
- 3.80 μm (cloud reflectivity at 2–3 bar levels)
- 5.10 μm (thermal emission down to 5-bar level)
Additional observations include 1.64, 1.65, 2.12, and 2.30 μm. From Nov 2016, Guidedog on SpeX was also used.
