RE: [comets-ml] Tail still long
- Hi Rob and all,
Yes, I did put down a couple of wrong numbers (lack of sleep I guess). Still, it does not make a very great difference. The revised length comes out at 39 degrees ... and this time I checked the numbers! The end appeared to be near Theta Carinae, visible with averted vision only in "flashes". Perhaps it was averted imagination, but I think it was real.

I'd doubt this will be correct. My photos show the tail much more
clearly than to the naked eye, up to 33 deg, just into Carina,
but I can't trace it crossing the dark zone to the SE of eta Carinae.
45 deg would take it over theta Carinae. Calculation error?

I'll reorganise this page in the next few days.
