There is a known issue involving a computation relating to sun angle in the GOES-16 Fire Hot Spot (FHS) code which causes processing to fall behind in certain blocks at certain times of day. The GOES-R science team is working on a fix which will be deployed in early 2020. This issue manifests as missing blocks that can be seen in the Data Quality Flag information of the product. This issue is intermittent but generally occurs around 2100z and generally lasts for 30 minutes to 2 hours.
