Time series of tropical Atlantic GOES-12 IR imagery, every 12 hours (at
00Z and 12Z) from 6-18°N, newest on top. Updated 8am and 8pm
MDT.

To estimate the speed of a propagating feature, if it moves toward the
left in subsequent frames (looking upward) at 10°/frame, that's
approximately 50kts.
If it takes two frames to traverse 10°, it's moving at about 25kts, etc.
