B2 1308+326: photometry and polarization during the outburst of 1978 spring.
Abstract
The results of visual, infrared, millimeter, and centimeter-wavelength photometry and polarimetry of the spring 1978 outburst of the BL Lacertae object B2 1308+326 are reported. The object exhibited a high degree of visual polarization that was rapidly variable in degree and position angle on a time scale of approximately 15 minutes (statistically significant at greater than 99.9% confidence). Following the maximum observed luminosity, the visual radiation declined more rapidly than the infrared. There has been a gradual increase in the flux density at centimeter wavelengths, but the relationship to the optical and infrared activity is unknown. Some implications of the observations are discussed briefly.
