The Galactic Plane Infrared Polarization Survey (GPIPS) has completed its second season of H-band (1.6 micron) data collection using the Mimir near-infrared instrument in linear polarimetry imaging mode on the 1.8m Perkins Telescope outside Flagstaff, Arizona. This key project for the Perkins Telescope seeks to answer important questions about the nature of the magnetic field and the aligned dust grains used to trace the field for small-scale star-forming regions, medium scale molecular and atomic cloud regions, and large-scale Galactic spiral arm and interarm regions. One of the goals for this season was to obtain polarimetry around a sample of the recently discovered Galactic bubbles in GLIMPSE. These bubbles have high eccentricities that suggests some astrophysical phenomenon is preferentially elongating them. Linear polarimetry of stars inside and outside the bubbles will trace the Galactic magnetic field and its interaction with these bubbles. This will help elucidate the interaction of the Galactic magnetic field with other dynamic forces.
