Hi All,

Based on the most recent elsets I can find, ISS is going to have
a close encounter with Solwind Deb AM on Thursday, July 29th at
about 4:46:55 UTC.  This encounter will occur over longitude +144.2,
latitude +5.1 (east-southeast of Palau Island) during the daytime,
so there will be no opportunity to view it from the ground.
Here's are the TLEs and output from COLA:

Ranges and orbital separations are in km.  ISS will be about 1.3 km
lower than the debris object, so there is virtually no chance of
impact.  --Rob
