February 17, 2003: Observing Jupiter and Saturn


Telescope: Tal 200K Klevtzov-Cassegrain, Location 50.55N 06.03E, Local time 21h.00m


It was a clear night again. Tonight I started off with Saturn. The Cassini division could be readily seen at 100x with a 20mm Vixen Lanthanum. The only detail I could detect on the surface was a dark zone in the equatorial region, probably the South Equatorial Belt. Five of Saturn's satellites could be detected immediately, Titan and Japetus to the west of Saturn and Rhea, Dione and Thetys grouped together closely to the East of Saturn. I did not detect Mimas and Encladus. They should have been very close to Saturn at that moment. Due to the nearly full moon, the limiting magnitude (telescopic) was about 11 to 11.5 magnitude using my 32mm Televue plossl.

At about 22h.05m local time I turned my telescope to Jupiter. I could detect several of the zones and belts. At a magnification of 166x (12mm Vixen Lanthanum) I detected the North Polar Region and the North Equatorial Belt, in between the two a large light zone with no detail. Then there was the South and North SEB (South Equatorial Belt), the South Tropical Zone, and a slightly darker zone from the South Tropical Zone right to the South Polar Region with no further details, zone's or belts visible. In the SEB the Red spot (hollow?) could be detected. In the Northern Equatorial belt, there was a knot clearly visible.
