AB  - We present the first reconstruction of the cosmic microwave background (CMB) lensing potential from the SPT-3G Summer survey using two years of temperature data. The Summer survey has a total area of approximately 2640 deg^2, split into three fields covering 1210, 570, and 860 deg^2, respectively. A joint analysis of the three Summer fields yields a lensing amplitude of A^comb = 1.014 ± 0.053 relative to a fiducial Planck 2018 ΛCDM cosmology for the multipole range 50 < L < 2000. These early results from the SPT-3G Summer survey highlight the potential for increasing the signal-to-noise ratio when combining the Summer fields with the SPT-3G Main and Wide fields for a total SPT-3G survey area of ∼ 10,000 deg^2.
