Drifting broken cloud is now interfering. In these worsening conditions all I seem to have detected is the central bar which appears as a 4:1 oval. There is a round core which seems to be double, the greater part to the E, the lesser to the W. I have failed to record the halo or any indication of the spiral arms.
