The disturbances in the STrZ are now visible in all 3 colours (as Ian Sharp already pointed out),though still a bit more in G than R,I think. Main spot now is now at III=324. There is also the SEBZ spot I reported in my last set just visible in red here,at III=32. In 4 days it has moved -25 deg.,corresponding to a drift of -6.25 deg. per day,similar to what Marc quoted.

On May 2nd I could finally capture some storm on Saturn for the first time this year. As a compensation-bonus, I captured the actual nice pair where the following spot is seen as a 45 deg tilted 8 shape.
Such a double spot is also seen in an image captured 8 (yeah, another 8...) minutes later, so I can fairly state it's real although the odd shape.
The preceding spot is less concentrated and fading over the W-E direction.
The poor transparency caused by thin cirrus lowered somewhat the color contrast. Seeing was steadily fair.
