All the times are in UT. Observations are presented in reverse chronology.Only positive or negative observations are compiled here, not clouded reports (sorry, too much work).For one observation, the first line is always :O+ : positive, O- : negative, O? : uncertain name of the observer Start observation End observation optics and aperture in mm method country longitude latitude altitude in m If the occultation is positive, or sometimes uncertain (O?), the second line is :duration in sec. time of Disappearance accuracy in sec. time of Reappearance accuracy in sec. time source reaction time for D in sec. (if visual) reaction time for R in sec. (if visual) A : reaction time applied, N : no reaction time applied (if visual) If multiple events are observed, they are processed as separate observations, but with a numerotation added in the first field (O+1, O+2...).If necessary, other lines in italic are added for comments.The character ¤ specifies the end of one observation description.


Abbreviations used are :

B : Binoculars CCD : CCD imaging
E : naked Eye PHG : photographic recording
L : Lens optics (refractor) PHM : photometer
M : Mirror optics (reflector) VID : video recording
VIS : visual
WEB : webcam recording
GPS : GPS receiver (no more info or only NMEA)
GPS+ : GPS NMEA with display correction applied
GPS++ : GPS one PPS
PHONE : Phone time signal (wired phone)
RAD : Radio time signal (no more info or only radio controlled clock)
RAD+ : Radio controlled clock updated just before event
RAD++ : Short or long wave radio receiver (acoustic signal)
TSS : Time synchronization software, through the internet (unreliable method)
TTV : TV teletext display
Note : for the best accuracy, only GPS++, PHONE or RAD++ should be used.
