The table below (check here for key) Urg: Degree of urgency of the observation. A: High. B: Low.
Day: Day of occultation.
UTC: UTC of occultation in Madrid (in black), Barcelona (green), La Laguna (red) and Marseille (blue).
Note that some events might be visible in some places and not in others (check column "OLED").
Star (WDS): ID number of star in WDS (Washington Double Star) catalogue.
RA: J2000.0 right ascension (hh mm ss.ss).
DEC: J2000.0 declination (dd mm ss.s).
Mags: Magnitude of components and total magnitude.
Year: Year of last observation.
# obs: Total number of observations.
Sep: Last measurement of separation between components, in arcseconds.
PA: Last measurement of position angle, in degrees.
Type: Type of occultation. I: ingress. E: egress.
Flux: Fractional change of flux in reference to combined flux. The two values refer to ingress or egress of each component.
Illum: % fraction of illuminated area of Moon (positive, waxing Moon; negative, waning Moon).
Def: Distance from contact to Moon terminator, in arcseconds.
γ: Position angle of contact in ° (from N to E).
hSun: Height of Sun above horizon in reference location at contact time, in °.
