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 characters |; specify 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), unreliable method
GPS+ : GPS NMEA with display correction applied
GPS++ : GPS one Pulse Per Second
PHONE : Phone time signal (wired phone)
RAD : Radio time signal (no more info or intermittent radio control. clock)
RAD+ : Intermittent radio controlled clock updated just before event
RAD++ : Permanent radio time signal
NTP : Network Time Protocol, unreliable method unless observatories (NTP++)
TTV : TV teletext display, unreliable method
Note : for the best accuracy, only GPS++, PHONE or RAD++ should be used.
