The Second Data Release of the Survey of the MAgellanic Stellar History
  (SMASH)
  The Large and Small Magellanic Clouds (LMC and SMC) are the largest satellite
galaxies of the Milky Way and close enough to allow for a detailed exploration
of their structure and formation history. The Survey of the MAgellanic Stellar
History (SMASH) is a community Dark Energy Camera (DECam) survey of the
Magellanic Clouds using $\sim$50 nights to sample over $\sim$2400 deg$^2$
centered on the Clouds at $\sim$20% filling factor (but with contiguous
coverage in the central regions) and to depths of $\sim$24th mag in $ugriz$.
The primary goals of SMASH are to map out the extended stellar peripheries of
the Clouds and uncover their complicated interaction and accretion history as
well as to derive spatially-resolved star formation histories of the central
regions and create a "movie" of their past star formation. Here we announce the
second SMASH public data release (DR2), which contains all 197 fully-calibrated
DECam fields including the main body fields in the central regions. The DR2
data are available through the Astro Data Lab hosted by the NSF's National
Optical-Infrared Astronomy Research Laboratory. We highlight three science
cases that make use of the SMASH DR2 data and will be published in the future:
(1) preliminary star formation histories of the LMC; (2) the search for
Magellanic star clusters using citizen scientists; and, (3) photometric
metallicities of Magellanic Cloud stars using the DECam $u$-band.
