[2.26] Near Infrared Vector Magnetograph Development

C. Gullixson, K. S. Balasubramaniam (NSO/SP - USAF/PL/GPSS), S. Keil (USAF/PL/GPSS)

We have developed a two etalon, narrow-band, tunable infrared filter system and are using it to make solar vector magnetograms in the Fe I lines at 1.5648 microns. We present results on the spectral and polarization resolution of the filter system and show maps of the magnetic field in both quiet regions of the solar atmosphere and in a region with a growing sunspot. We will discuss the magnetic sensitivity of the instrument. This system is a prototype instrument for a operational vector magnetograph that will monitor the evolution of solar magnetic fields preceding solar activity.
