Suomi NPP and NOAA-20 view Tropical Depression Alberto over the lower Ohio River Valley
Day Night Band Visible (0.7 µm) Imagery from Suomi NPP (0722) and NOAA-20 (0812 UTC) over Tropical Depression Alberto (Click to enlarge)
Suomi-NPP and NOAA-20 overflew tropical depression Alberto, at 0722 and 0812 UTC, respectively (orbit paths from this site), on 30 May 2018, and the near-Full moon provided ample illumination for the Day Night Band imagery, shown above. A motion to the northeast is apparent. Convection developed far to the north of the storm as well, south of Chicago, and a streak of lightning occurs over Oklahoma in the later image.

A tip of the Hat to Will Straka, CIMSS, for the imagery.
