All the
times are in UT. Observations are presented in reverse chronology.
All geographical coordinates should be expressed in WGS84 datum.
Only positive or negative observations are compiled here, not clouded
reports (sorry, too much work). Unless
clear positive or special event, reports about events with predicted max
duration <1s are stored but not published on these pages.
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 | long
lat datum (W : WGS84) alt datum (W : WGS84, S : Mean Sea Level) |
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. In the case of a double star, a numerotation is added in the first field (O+1
for the primary star,
O+2 for the secondary star).
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 or CMOS 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
LAC : Local atomic clock
NTP : Network Time Protocol (no more info or Windows sys), unreliable method
NTP+ : Permanent NTP synchro under Linux/Unix sys
NTP++ : Permanent NTP synchro with local atomic clock (observatories)
TTV : TV teletext display, unreliable method
Note: for the best accuracy, only GPS++, PHONE, RAD++, NTP++ or LAC should be
used.
