We use daily full-disk vector magnetograms from Vector Spectromagnetograph(VSM) on Synoptic Optical Long-term Investigations of the Sun (SOLIS) system tosynthesize the first Carrington maps of the photospheric vector magnetic field.We describe these maps and make a comparison of observed radial field with theradial field estimate from LOS magnetograms. Further, we employ these maps tostudy the hemispheric pattern of current helicity density, Hc, during therising phase of the solar cycle 24. Longitudinal average over the 23consecutive solar rotations shows a clear signature of the hemispheric helicityrule, i.e. Hc is predominantly negative in the North and positive in South.Although our data include the early phase of cycle 24, there appears noevidence for a possible (systematic) reversal of the hemispheric helicity ruleat the beginning of cycle as predicted by some dynamo models. Further, wecompute the hemispheric pattern in active region latitudes (-30 deg \le \theta\le 30 deg) separately for weak (100< |B_r| <500 G)and strong (|B_r|>1000 G)radial magnetic fields. We find that while the current helicity of strongfields follows the well-known hemispheric rule (i.e., \theta . Hc < 0), H_c ofweak fields exhibits an inverse hemispheric behavior (i.e., \theta . Hc > 0)albeit with large statistical scatter. We discuss two plausible scenarios toexplain the opposite hemispheric trend of helicity in weak and strong fieldregion.
