The images already discussed in the chapter on frontal diagnosis (compare Overview of satellite imagery for 06.00 UTC ) shows several changes in the area of the cloud bulges north-north-west of the frontal cloud bands. With satellite imagery alone and without knowledge of the genesis, a Rapid Cyclogenesis can still be supposed but its location is still not quite clear. Relaying on the information already derived for 00.00 UTC and on the Black Stripe in the WV image of 06.00 UTC, a Rapid Cyclogenesis can be presumed more in the centre of the huge cloud shield as well as a Comma feature in the south-western part of it.
