We show first results derived from one month or more of GONG++ data analyzed with a ring-diagram technique as part of the GONG++ local helioseimology analysis pipeline. We focus on observations obtained during spring 2002 and especially on Carrington rotation 1988 (2002/3/30 - 2002/4/26) and measure horizontal flow components over a range of depths up to 16 Mm on a spatial grid of 7.5 degree in latitude and longitude. We calculate zonal and meridional flow components and compare the average zonal flows with corresponding results of a global rotation inversion. We create and analyze synoptic maps of large-scale flows and compare them with corresponding synoptic maps of magnetic activity. We will present the latest results.
