Saturn is shown here 1 month past its 2025
opposition with Earth.
Atmospheric seeing conditions for this
session were poor (4 out of 10) with jet stream turbulence present
overhead complicated further by low planet altitude in the sky which
caused some blurring effects from atmospheric dispersion.
The rings of Saturn are currently showing a very
severe closure angle in 2025 as Saturn reaches the part of its orbit
around the Sun that puts it directly in an edge-on visual alignment
with Earth.
As Saturn continues its orbit around the Sun,
the rings will gradually open back up and become much more visible.
Features such as the Cassini and Encke ring divisions will be much
easier to observe then.
