| Mode: | Grism | ||
| Additional instrument verification: | These observations test the ability to use the OIWFS to keep a faint non-sidereal object accurately positioned on the slit. | ||
| Telescope verification: | The telescope must track accurately on a faint, non-sidereal object. This mode will probably not be offered in the first semester. | ||
| Proposed observing sequence: | not available | ||

| Science background: | Low-Resolution NIR Spectroscopy of a Kuiper Belt Object We propse to obtain low resolution grism spectroscopy of a Kuiper Belt object to study the composition of its surface. The observations will demonstrate Gemini/NIRI's capability to fast guide while following a moving object. The ability to keep the object in a narrow slit is essential for the success of these observations. Kuiper Belt objects with K~20 are extremely faint for spectroscopy and will require NIRI to perform fully to its specifications. |
