Nearly there

 

Fourth contact is only seconds away.

 

 

 

Black Drop images

 

A lot of bad things have been predicted about the Black Drop or Gutta Negra. With all our nice equipment this Venus Transit the matter could be close. The observers had different ideas whether the Black Drop was visible this time. At the time of second and third contact report of negative observation were filed. With webcam images and movies we are now able to "replay" the crucial images around second and third contact. Preliminary analyzing the reports it looks the important factor for observing the Black Drop is magnification. Is it instrumentation, optical illusion or wishful thinking still needs to be settled. The day after the Venus transit I took part in an online survey by Stephen McCann trying to test the different assumptions. With observers all over the globe with a multitude of instruments the answer must be out there...

This was my reply to the survey :

Black Drop at ingress: YES

Black Drop at egress : YES

Instrument : 10cm SCT

Place : Luxor, Egypt 2541'N, 3239'E

To  illustrate my observations I took  some images from the webcast. More images will follow from the AVI's (image every second) 

Black Drop at ingress

Black drop at ingress. The Omega shape is visible. Nearly 2 minutes of Black Drop.

Please come back for ingress Black Drop movie (05:37:00 to 05:39:10)

 

Black drop at egress. Very small black extension from the Venus disk to the edge of the Sun. On the movie the channel could be seen to "grow". 

 

For the egress Black Drop I concede that it possibly was the Venus atmosphere and not an optical illusion. Please come back later for a short movie (11:04:30 to 11:05:00) of the third contact.
