Abstract: Recent results regarding subpulse drift in pulsar B0943+10 have led to the identification of a stable system of sub-beams circulating around the magnetic axis of the star. Here, we present single-pulse analysis of pulsar B0834+06 at 35 MHz, using observations from the Gauribidanur Radio Telescope. Certain signatures in the fluctuation spectra and correlations allow estimation of the circulation time and drift direction of the underlying emission pattern responsible for the observed modulation. We use the cartographic transform mapping technique to study the properties of the polar emission pattern. These properties are compared with those for the other known case of B0943+10 and the implications are discussed.
