HD 25443 is a very hot, normal star seen at great distance through much interstellar matter. Ground observations show it to have a very large polarization (5.2 times the interstellar absorption). It will be used by WUPPE to compare the different ultraviolet polarization signals obtained through various methods. In addition, it will be used to verify the UV signal throughout the flight.

The the observations made were analyzed along with the other stars in the WUPPE interstellar medium polarization program. See our paper in AJ 112, 2726 1996.
