A good Virtual Face 2 Face meeting of the DM leadership team was held on June 22,23 as usual a variety of technical topics were discussed as well as status and planning.

A Kafka broker to test the alert streaming service was set up. Regular reprocessing of the DECam HiTS dataset now includes crosstalk correction using Gen 3 middleware, marking feature parity between Gen 2 and Gen 3 for AP.

The Solar System team created and distributed the mock Solar System Object Catalog.

The measurement plugin implementing Gaussian Aperture and PSF Photometry (GAaP) for measuring galaxy colors [dmtn-190, [Kuijken+15]]([1507.00738] Gravitational Lensing Analysis of the Kilo Degree Survey) was completed. Preliminary results show colors of simulated (DC2 ImSim) red galaxies are better recovered compared with CModel colors.

NCSA set up and continue monitoring of data transfers and ingests through the Transfers and ingest monitoring system (TIM).
