On 1 February 2019 a meteorite exploded over Western Cuba near Viñales in bright daylight, as seen in GOES imagery.

Using GOES-16 Volcanic Ash RGB imagery it was possible to track the speed of the debris before it made impact in western Cuba. Figure 1 shows that the meteorite debris travelled in the atmosphere at a speed of ~45 km/h.
The impact site can be seen in the GOES-16 Volcanic Ash imagery, 1 Feb 18:17 UTC (Figure 2).
Meteorites can be composed of a number of materials and using the GOES-16 Volcanic Ash RGBs it is possible to see if this meteorite contained any sulphur-related materials. Sulphur shows up as bright green in the Volcanic Ash RGB and on this animation of the RGBs, in five minute intervals between 18:02 UTC and 19:32 UTC (Figure 3), there was no significant SO2 signal visible, so, most probably, the meteorite did not contain significant amounts of sulphur-rich material.
