RE: Catching Comet Wirtanen this December

in #steemstem • 6 years ago

Thank you Terry :-)
I am very curious about his appearance. But also if I can do it. That would be the first attempt with Goto tracking on a comet. I should be able to get the coordinates from planetarium software. However, I don't know where I can get the speed to the tracking rate. Do you have a tip for me?

    Hi Kevin, try JPL Horizons which can output RA and Dec rates for you. But to save you time I ran it for December and here are the rates in arc sec per hour.
