The first interesting object i observed was Globalstar 22 r1 #25653 at 06:40
13 Jun UTC. It has a nice tumbling pattern as it went from a mag 2 to mag 3
and then to invisible and it would repeat the cycle.

Meteor 1-2 r #04120 came by at 07:14:08 13 Jun UTC +/- 2 sec at Azim 95
degrees Elev 55 degrees. It was predicted to be mag 1.5 but it was only an
est mag of 3 but flared briefly to about 1.5. Not a spectacular pass for one
close to re-entry. This elset was used:

I observed Irid 14A CSL02 S/D #25780 at 07:58:15 13 Jun UTC +/- 2 sec at
Azim 270 degrees Elev 54 degrees. The predicted pass time at Az 270 was
07:58:21. The mag increased once it passed due West Southbound to a mag 2.

A short time later, at 07:59:35 13 Jun UTC +/- 2 sec came the trailing Irid
14A CSL02 r #25779 at Azim 270 degrees Elev 51 degrees. Only 3 sec ahead of
it's predicted time. It's mag increased to a brighter mag 1 as it began it's
Southbound track.

Both were moving quickly and these elsets were used:

Irid 14A CSL02 r                                 654 x 178 km

I looked for Starshine #25769 but it was too light out to get a firm
sighting and i was looking too high. I also looked for Iridium 14A and 21A
at 1x but nothing so they seen to be in a stable orbit, for now at least.

As i was about to send this i noticed ISS #2554 was to come by so i went out
to look and saw Lacrosse 3 r #25018 leading it by about 20 degrees. As i
watched ISS i noticed a bright flash about 1-2 degrees behind it. I didn't
get a timing but it was at roughly Azim 170 Elev 30 degrees. ISS predicted
peak was Azim 161 degrees Elev 35 degrees at 08:51:52 UTC. Could that have
been Starshine?
