--> EXPLANATION OF SYMBOLS/TERMINOLOGY <--
1) Mag.: Magnitude; degree of brightness of star/object/etc.
Magnitude 1 is brightest, although some stars/planets/
etc have Negative Magnitudes (These Are VERY BRIGHT)
2) Angular Size: Size of object as viewed through telescope (?)
Measured in degrees of arc. (Is This Correct?)
3) % Illum.: Percentage of surface illuminated by solar light.
4) Earth/Sun (AU): Distance to object (planet) as measured from
either Earth or Sun. An "AU" is Astronomical
Units (distance of Earth from Sun). Roughly
this figure is rounded to 93 Million Miles.
5) R.A./Dec.: Right Ascention/Declination of star/planet/object;
Right Ascention is measured in time units where 24
hours equals 360 degrees. When the first point of
Aries culminates the time is 00h 00min.
Declination; Celestial Latitude. North Celestial
Pole has a declination of N 90 degrees (*)
Satellites of Jupiter (4:00 UT)
(As Seen Through Refracting Telescope)
[ Jupiter=0, Io=1, Europa=2, Ganymede=3, Callisto=4 ]
