The following is a summary of the latest updates to my Decay Watch page,
including the first notice for a decaying low-inclination Ariane rocket
and corrected eclipse circumstances for Iridium 9.

SatEvo prediction: None at this time.
Note: My previous update reported incorrect data for the eclipse
entry and exit circumstances of this object. In fact, this enters
eclipse southbound near 78 deg N at ~21h local time. Eclipse exit
occurs southbound near 65 deg S at ~23h local time.

Note: I predict that this low-inclination object will decay over
Brazil following perigee on the final predicted orbit above.
