USA 184 Trumpet (?) ELINT and more

Yesterday in the daytime, it was clouded and rainy. It cleared marvelously in the evning though. I detected the clearings too late to capture the evening Keyhole passes, but captured a number of other objects: IGS 1B (03-009B, a defunct Japanese SAR), Lacrosse 2 (91-017A, a SAR as well), the NOSS 3-3 Duo (05-004 A & B), and two HEO objects: USA 184 (06-027A) and the USA 144 decoy (99-028C) again.

The image below shows the USA 144 decoy again, and is a somewhat better picture than that which I posted in a previous post:

USA 184 was imaged as well, and for the first time by me. It showed up bright. It is probably a Trumpet-class ELINT satellite. It is in a Molniya orbit (see below) and at the time of imaging was at an altitude of 28560 km, over Northern Europe.

Below is one of the images, plus an animated GIF of all five images, showing the movement perpendicular to the night sky rotation:
