behalf of a larger collaboration:

We observed at the transient AT2019wxt (PS19hgw; McBrien et al., GCN 26485)
using the Large Monolithic Imager (LMI) on the 4.3m Lowell's Discovery
Channel Telescope (DCT) at Happy Jack, AZ. Observations started on December
20, 02:43:34 UT with SDSS g,r,i,z filters.

We detected the source with the following preliminary magnitudes:

Start Time        Exposure    Filter    Magnitude

58837.114          3x150          r'    19.43 +- 0.02
58837.120          3x150          i'    19.62 +- 0.01
58837.126          3x150          z'    19.58 +- 0.03
58837.126          3x150          g'    19.86 +- 0.02
-------------------------------------------------------

Magnitudes are in the AB system and are calibrated are calibrated against
SDSS catalog.

We thank the staff of the Discovery Channel Telescope in particular Casey
Kyte, Stephen Levine and Ishara Nisley for assistance with these
observations.
