In December 2009, the camera was upgraded again for the 2010 observing season. The full 2500 square-degree SPT-SZ survey was completed during the 2010 and 2011 observing seasons with winter-overs Dana Hrubes and Daniel Luong-Van. First light (the first observation) with the SPTpol camera was achieved on January 27, 2012. During the first season of observations, the winterover crew, Cynthia Chiang and Nicholas Huang, took data on a 100 square degree survey field. 2013 winterovers Dana Hrubes and Jason Gallicchio surveyed a larger field as part of the full SPTpol survey. This larger survey was completed by 2014 winterovers Robert Citron and Nicholas Huang, 2015 winterovers Charlie Sievers and Todd Veach, and 2016 winterovers Christine Corbett Moran and Amy Lowitz. The first winter of SPT-3G observing was conducted by winterovers Daniel Michalik and Andrew Nadolski, with Adam Jones and Joshua Montgomery following in 2018, and Douglas Howe and David Riebel in 2019.
