SweetSpot was a 3-year NOAO Survey (2012B-0500) that collected 114 Type Ia Supernovae (SNeIa) located in the nearby smooth Hubble flow. The survey observed over 88 nights using the WIYN High Resolution Infrared Camera (WHIRC) mounted on the WIYN 3.5 m Telescope located on Kitt Peak. The goals of this survey were to:

1. Extend NIR Hubble diagram out to z~0.08
2. Quantitatively test how standard SNeIa are in the NIR
3. Provide insights into the color involution of SNeIa
4. Study dust in other galaxies
5. Explore correlations of NIR SNeIa with host galaxy properites
6. Provide a well-calibrated low-redshift anchor for future, potentially space-based surveys
