Red Spot Transit Times

[Stub Mandrel]

The various sites  claiming to predict the transit of the GRS are not in good agreement.

Calsky and Sky and Telescope are only two minutes apart at the moment but for 14 June their predictions are 61 minutes apart.

Any suggestions for the most reliable predictor?

I know that one, about 10 minutes off the others at the moment, but uses 2 degrees a month.

I can't figure how S&T drifts so far in one month given its rate is only 0.75 degrees less than the others - the hour difference is about 36 degrees

I use GasGiants iPhone app... seems to be accurate for the GRS and moons. 

It predicts Jupiter, Saturn, Uranus and Neptune.
