Okay, solar system folks...….
I have a question inspired by 46PWirtanen. I had never recalled seeing it before, even hearing of it. I have been observing for some time. I would have known.
It is quite visible in my 15 inch Dob, and even the finder scope for it. Got a pretty good pic of it in the imaging camera, although I have not yet processed to confirm. So, it is obviously observable...….
In looking it up, I notice it has a periodicity of 5.6 years. Ok, so if it is so bright, and comes around every five or six roughly years, how come it has not come to my attention before? Or------to put it in other terms------Does a comet have approximately the same observability each time it comes around, or does it vary a bunch?
