Puzzle 3: Starchart

In the middle passages you'll find a library. Inside the library is a starchart, you'll need to study it a few times but then you'll get something like this:

xxxxxx stares blankly at the wall map for a long moment. Just when you are ready to bet good coin that she's lapsed into a meditative state, she blinks, an expression of dazed enlightenment spreading slowly across his face and he announces that each marker can be locked into position at various points along the tracks.
Syntax:
PUSH <SEASONAL> MARKER -- Slide the marker forward along its track.
PULL <SEASONAL> MARKER -- Slide the marker backward along its track.
TURN <SEASONAL> MARKER -- Attempt to lock the marker in its current position.
LOOK STARCHART -- View all markers, positions, and locked status.

The starchart looks like this -

Carved into the wall is a large representation of the Elanthian sky engraved with a series of concentric circles into which metal markers have been affixed. Time and the elements have taken their toll on the starchart and gauging its age and condition you wonder if it's entirely accurate. Four of the markers have been engraved with the name of a season, while the final and outermost marker slides along a track positioned to indicate heavenly bodies visible throughout the year. It appears that each marker is capable of both sliding freely along its groove and being fixed into place at positions corresponding to the various astrological paths of heavenly bodies.
The winter marker points to The Shrike and is in an unlocked position.
The summer marker points to nothing in particular and is in an unlocked position.
The autumn marker points to nothing in particular and is in an unlocked position.
The spring marker points to nothing in particular and is in an unlocked position.
The yearly marker points to nothing in particular and is in an unlocked position.

On the desk in this room is a journal divided into the seasons. You'll need to find some reference to a matching symbol in each section of the journal. I'd expect this one to change also but our answers were

The winter marker points to The Shark and is in a locked position.
The summer marker points to The Scales and is in a locked position.
The autumn marker points to The Lion and is in a locked position.
The spring marker points to The Dove and is in a locked position.
The yearly marker points to Heart
