Hi, I just read about measuring central meridian transits of features on Jupiter. I’m curious to know if anyone has tried it ? Any tips?
Tips on measuring central meridian transits on Jupiter
Posted Today, 12:14 AM
I've been doing CM timings since 2009. The GRS, barges on the NEB, Oval BA, White Spot Z, and festoon bases on the NEBs. I collected the data on these features and recently because of having time on my hands ( pandemic), I charted the data on some graphs.. I'm currently working on determining the rotation rates of the features I timed. It's a fun way to learn more about the fascinating planet Jupiter.
Have a good timepiece by the scope along with clipboard, and light to record your timings.
A clock drive can help but not necessary.
Use a moderate to high magnification.
On large features, time the preceding, center, and following edge of the feature.
Here's my drift charts for the GRS.
I hope you find this useful.
