At 0315Z center of convection is located near 9.5N / 37.5W. Lightning has increased quite a bit over the last 3 hours. Diurnal convection-probably.
Strange formation to the main cloud area. While the lower level clouds would suggest the larger 'main' cloud is over the center of circulation. A semicircular notch exists to the NW side of the 'main' cloud. Resembling a 3/4 "Eye". No rotation about this notch is visible.
(Thanks to SSD for the Lat/ Long Grid overlay for this area of the Atlantic)

Current Dvorak cloud temperatures are in the -64 to -69C range. (colored as black). A short period of higher cloud tops existed around 0215Z. With the Dvorak indicating cloud tops in the -70 to -75C temperature range. (colored as white).

Current motion appears to be WNW near 15 knots.
