Observations were taken at the NSO/KP McMath/Pierce Telescope using a new 256x256 HgCdTe array camera as part of a collaboration between NSO and Cal State University Northridge. Spectra of the He I 1083nm line were taken between 17:36-18:06 UT on 22 Mar 2002 of the active region NOAA 9877 near the west limb. Doppler shifted flows of +/- 50 km/sec are seen near the active region sunspots. Line emission from an erupting prominence is also seen in these data above the west limb; rapid transverse motion as well as Doppler shifts of +/- 100 km/sec and greater are observed. Sample data and a more detailed analysis will be presented.
