Venus from May05 to May10 by A.Cidadao |
Dear sirs, I attach〓a mosaic containing daily〓Venus images from May 05 until May 10, with the main goal of attempting to visualize again the "linear" cloud pattern ("cloud discontinuity"???) I had observed and reported on May5. In addition, for three days (May 6,7,8) , gif animations of images obtained at about 1 to 2 hour intervals are also included/reported to demonstrate retrograde atmospheric rotation. The filter used was always the Baader SLOAN z'-s' IR band. Unfortunately, seeing conditions were not always favourable. All images were obtained in daylight. The return of the same IR cloud patterns was not observed, namely a replica of the linear cloud feature observed on May 5 (cloud discontinuity???), but on May 9 a distinct "C-shaped" feature with two "horizontal" and one "vertical" linear components was seen.〓 I have no idea that, given the putative IR cloud layer dynamic behavior, if the above referred〓cloud patterns observed on May 5 and 9 correspond to the same event. ≪アントニオ シダダオ ポルトガル≫ [Antonio Cidadao Oeiras - Portugal]
