hello all,
because of terrible wheather over Europe during the last two weeks,
only some observations of Gorizont 23 = 21533 = 91- 46 A were made.
These clearly confirm the third observed acceleration of this object.
Right now it is becoming visible over America, so who takes over ?
It should be flashing with maxima to about +6, so an easy binocular
target.
91- 46 A 99-12-07 JPH 51.59

[observations from Jason Hatton, Michel Jacquesson, Patrick Devreese
and myself]
On my webpage I updated the graph and also added
ETS-6 = 94- 56 A = 23230 which has been observed accelerating
for nearly three years now from 21 to 11 seconds.
It seems that the speed of acceleration is going down and the
period is nearly constant now, so probably it will start to decelate
in the near future.
Michel Jacquesson also reports the period of 91- 14 A
= Raduga 27 = 21132 to be going up fast, it was flashing
with 69 seconds on Oct 18 and has already reached
90 seconds on Dec 21.
cheers,
Kurt
