Re: Centaur tumble(2007-27B/31702)

This evening I observed the object again over Belgium at 19:11 UTC.

It is definitly in an end over end tumble but not with 5s buth rather
15s.(I missed the last maxima due to some clouds so the accuracy is not
that good but much better than yesterday)  Bright round maxima with regular
intervals.  In PPAS format I would say A'A', mag max +2.5.

Ik hope to see some other observations real soon.

gr, tristan cools
