Instellar reddening in a high-latitude field around Omega Bootis
UBV observations have revealed an interstellar cloud with a visual totalextinction of 0.2 mag and a diameter of 1.5 pc at 60.5 deg galacticlatitude near Omega Bootis. The distance to the cloud is estimated atabout 25 pc. On the basis of the reddening values and by taking thebackground component into account, the intrinsic polarization of thecloud is calculated to be 0.0082 mag. The cloud's mass in neutralhydrogen is estimated at roughly 7 solar masses.
