Sun Time lapse over 2h 35m on the old cycle 24 spot

Post by rsfoto »

Hi,

Finally I was able to finish a time lapse I made on the old cycle spot. The mounts tracks good at custom speed on the Sun which I found out after a few days of experimenting.

Sidereal rate is 15.041 arcseconds per second

Calculated Solar rate is 15.0 arcseconds per second

but the really Solar rate for keeping the Spot more or less in the center is 0.9965 x 15.041 = 14.988 arcseconds per second, when the Sun is at DEC -23° to -21°at least at my location at 22° North.

Thanks for looking

Great work Rainer. Looks very clear/crisp.

You really managed to capture the changes (over time) in the AR quite nicely.

That's excellent Rainer! I see the palm tree makes an appearance too. Interesting about solar rate too.

Excellent timelapse, it shows there isn't much going on in this old cycle AR . Even though the new cycle ARs are small they tend to be much more active.
