J/A+A/314/312 Galilean satellites mutual events in 1997 (Arlot 1996)
Predictions of the mutual events of the Galilean satellites of Jupiter occurring in 1997 Arlot J.-E. <Astron. Astrophys. 314, 312 (1996)> =1996A&A...314..312A (SIMBAD/NED BibCode)
ADC_Keywords: Planets ; Occultations Keywords: satellites of Jupiter - ephemerides - occultations Description: This paper provides the predictions of the mutual phenomena of the Galilean satellites which will occur in 1997. Past experiences have shown the interest of the observation of such events very rare, since they occur only every 6 years when the Earth and the Sun pass through the common orbital plane of the Galilean satellites.

Note on table1-9: The dates are given in Terrestial Time (TT), which is near the former Ephemeris Time. At the time of the events, the difference TT-UTC will be about one minute of time. Therefore, to get the date of an event, one could substract one minute of time from the dates of the table.

Distance of the eclipsed or occulted satellite to the center of Jupiter in Jovian radii in order to know the configuration during the observation 41- 45 F5.3 arcsec Impact Impact parameter i.e. the minimum distance between the satellites during the event (distance to the shadow cone for eclipse)
Note (1): 1O2 means that J1 will occult J2 3E4 means that J3 will eclipse J4 C means close approach with probably not magnitude drop observable P means partial event A means annular T total nothing is indicated in case of an eclipse by the penumbra Note (2): 1: total desappearance 0: grazing event with probably no detectable magnitude drop Note that the flux drop is calculated referred to the light flux of both involved satellites in case of an occultation and to the light flux of the only eclipsed satellite in case of an eclipse Note (3): 1: occultation of J3 by J2 on April 6, 1998. This double event will occur as follows: first contact at 14h 54m 50s, first maximum of the magnitude drop at 15h 39m 0s, increase of the light flux until 17h 21m 0s (the two satellites are than near the external contact but always overlapping), second maximum of the magnitude drop at 19h 25m 18s and final external contact (end of the occultation) at 20h 20m 12s.
