The first light scan of NOAA 10953 from April 30, 2007, taken with the infrared arm of FIRS. Shown are maps of the infrared continuum intensity(top left) and Stokes Q(top right), U(lower left), and V(lower right) derived from the 15648 Å Fe I line. Click on the images to see the movie showing the data cube reconstruction of these scan maps in continuum intensity, and Stokes Q, U, and V. A cracked bandpass filter that has since been replaced is the cause of the noisy diagonal stripe across the lower portion of the image. The images are reconstructed using data from all four slits, yeilding an area of approximately 160 x 70 arc-seconds.

These images are the result of a simultaneous infrared and visible scan of NOAA 10999 from June 17, 2008. The first set of images are the infrared continuum intensity and Stokes Q, U and V dervied from the 15648 Å Fe I line. The lower set of images are the visible continuum intensity and Stokes Q, U, and V derived from the 6302 Å Fe I line. The sunspot was small so these data come from a single slit covering and area of approximately 40 x 70 arc-seconds. The visible map is out of focus, the focus for this arm has been improved significantly since this map was taken. The visible and infrared full Stokes spectra from a position roughly halfway across the sunspot are shown to the right of the maps.
