Saturn appears calm. No storms evident. Mimas and shadow are actually in transit although certainly not resolved.
[Gary Walker:Georgia:USA]
この時期としては比較的シーイングは良好であった。R,G,B分割撮影も試みた。
小口径（200㎜）の望遠鏡のため，解像力は十分ではないが，色調は豊かであった。

Seeing 9/10 Trans 9/10
Presented in Johnson/Cousins Ic filter:
- processed image of Saturn.
- amplification of the intermediate image of Saturn (contrast,brightness,shadow level).
- equatorial region by ephemeris.
Prometheus (Saturn XVI) has a relatively high albedo (0.6),mag - 16.4.
[Serge Dramonis : Athens,Greece]
I have been lazy to run derotation so there is none here.
The idea for me was only to take a look at the colors. On the southern winter hemisphere,the blue-absorbing chromophores are still not active,and at the result the colors are cold like in 2022.
Green,pink,violet,some really rare colors for such a yellow planet! Let's see if this evolves during the course of the apparition.

[Jean-Luc Dauvergne:Paris France]
The seeing was fair. Nothing remarkable was noted and the planet remains quiescent.
