RESULTS FROM THE TRANSIT OF VENUS EXPEDITION TO DARVAZA, TURKMENISTAN, JUNE 6, 2012
We observed the Transit of Venus from very close to this giant gas crater at Darvaza, 70m in diameter and 20m deep. On one evening I was looking at viewing predictions downwind from the gas fumes and a gust of wind pulled those predictions up into the air and down into the crater, never to be seen again.

RING OF FIRE EXPEDITIONS succeeded in observing the second and last Transit of Venus of the 21st century from near the remarkable gas crater at Darvaza, Turkmenistan. Our group of 16 persons plus guide and support staff set up camp about 200m south of the crater to take advantage of the prevailing wind and to enable all participants to observe from their tents. We had traveled for the previous 13 days from Kazakhstan to Kyrgyzstan to Tajikistan, and Uzbekistan before arriving here.

On transit day skies were 100% clear with a wind from the east at 15 to 20 knots and temperatures in the low 80’s F. At sunrise the transit had been in progress for several hours so we were able to observe it from 5.38am local time to 9.53am which corresponded to last contact (whenVenus was no longer visible). Seeing conditions were quite good except near the horizon. Note that we had clear skies for 12 of the 14 days on our tour.

Our camp at Darvaza just before sunrise June 6. The sun came up to the left of the hill where several members watched the sun before the rest could. C.Pinales describes being able to view the Transit naked eye for <30 seconds as it popped above the horizon at a depressed horizon angle.

In order to overcome the wind conditions toward the last two hours of transit viewing I had to place my Meade 2045D inside the tent. Prior to doing this, the wind actually blew the Baader filter material out from in front of the objective and I had to chase it down the road.
The following images are from Jeff Pohlman. They are the best of the best on this trip. The specifications of these excellent photos are:
The above image shot by Jeff does NOT show the Black Drop. His site was just adjacent to P.Maley. This suggests that the Black Drop is more instrumental than anything else and not necessarily a function of local seeing.
