Occultation of iota Cancri by (411) Xanthe April 18 UT at Valdosta, Georgia - New 2007 April 18, 21h UT

The 6-second occultation video recorded there, 5 km north of the predicted northern limit, shows that the path shifted at least 15km north of the prediction

confirms north shift 

Kyle,
     Many thanks for this; with this relatively short chord obtained 
from Valdosta at 43 km north of center, and a few km north of the 
predicted limit, along with the other several observations from 
Florida, we'll be able to determine the shape of Xanthe quite well.  
It also seems consistent with the 15-km north shift of the actual 
path from the predicted one that we estimate from observations made 
in the southern part of the predicted path. I also give below your 
message one from Martha Leake that gives some more information about 
the VSU observation.

Dear Dr. Dunham

    Hello, I am working on reviewing my video I made of the 
occultation at 8:56 p.m. EDT Tuesday April/17/2007. I live in Valdosta 
and I did my observation at Valdosta State University. Interestingly 
enough, even though we were not supposed to see the occultation, we 
did. I am going to try getting as accurate of a reading as I can. As 
of now, by use of stop watch, I timed it at 6seconds and 1/50th of a 
second. I hope this will help you. I will get the video to you soon. 
Thank you for opening this opportunity to everyone.

David,

At the observatory at VSU we did indeed see a short occultation of 
iota Cancri A, beginning about 8:57 pm EDT. Our timings will be more 
exact after we analyze the video tape made of the occultation. Our 
location is 30 50 53 N and 83 17 20 W (using TpooZone), with 
elevation at the base of the building 195 ft, and on the fourth 
floor, about 45 ft more, or 240'. We observed through the 16-inch 
and a 6-inch, and clearly saw the brighter star occulted (fainter 
star still visible). These data are preliminary, but exciting, 
nonetheless.
