Starting with the first orbit of 9 October 2017, the MHS data from NOAA-19 began displaying substantial artifacts. After the orbit crossing 00 UTC 10 October, the NOAA-19 data have been embargoed from Early and Late IMERG, although it took until 03 UTC for all artifacts to age off the morphing. At this point, Early and Late IMERG appear nominal, except they lack the sampling that NOAA-19 provides.
