My new Excel spreadsheet that enables me to analyze the data.

The raw list from the MPC.

I wanted a good handle on this. Yes, the MPC maintains a list, BUT it is hard to analyze. So, I used that data to create one of my SPECIAL Excel spreadsheets. Now I can slice & dice the data at my will.

The MPC list has 872 valid entries! That is a LOT.

C/2020 F3 (NEOWISE) was the brightest — albeit based on a July 13, 2020, reading. Well, that is now way obsolete. The brightness of C/2020 F3 (NEOWISE) is NOW above ‘5’. It has to be ‘5’ or BELOW to be naked-eye visible. So, none of these 872 comets are naked-eye visible.

The next brightest, periodic, 2P/Encke, is at 10. That puts it even beyond binoculars.

So, a heads up. No point looking up. No naked-eye visible comets at present. SMILE.

That is why C/2020 F3 (NEOWISE)  was so special.
