解説（安達）/ Comment by Makoto Adachi
An interesting morning session as I had extreme variations in seeing conditions.
After nice conditions for Saturn,I just managed to catch these single R,G and B's as the seeing dropped off a cliff.
The rest of the RGB was terrible,and I was about to close everything down when I noticed a slight improvement as I captured the final attempts at IR.
I still have to process the Jupiter results,but it looked like the seeing may have recovered significantly towards sunrise.
Syrtis Major and Hellas dominate the view and it seems that there is significant brightening in the northern section of Hellas.
The Perseverance rover region looks reasonably clear.

Dear Sirs,a low-res image due to below-average seeing,with Hellas at the terminator.
My impression is that no particularly intense dust accumulation is seen.

Difficult conditions with pernament changes between an almost clear to almost fully clouded sky together
with turbulent air resulted in several attempts for an RGB set. As an exception,I dediced to present all images.
They illustrate the degree of variation in appearance due to both rotation/lighting on Mars,and the seeing on Earth.
G & B channel qualitiy deteriorates quickly with brightening daylight.
For the set around 4:00 UT a derotation with RGB composition was made. Hellas definitely appears bright,
but the effect is most prominent in R.
So its is probably due to surface albedo changes after the dust from the recent storms in that area has settled again.
The generally high contrast favours the assumption of a clear atmosphere.
The SPC appears remarkbly less distinct in R compared to G & B.

上空の大気の状態がよくなかったので、鮮明な画像を得ることができなかった。RGBフィルターによる分割撮影とした。
The air quality was not good enough to obtain a clear image,so a split shot was taken using RGB filters.

良く晴れましたが、高度が上がるほどシーイングが悪化する感じでした。
