Solar Returns are absolutely fascinating.
My partner's SR chart covering Sept 05 to Sept 06 had Saturn on the Ascendant and 29 Aries on the MC with Mars in the 10th and the Sun in the 3rd. Sure enough, he was quite suddenly offered a job late in the year (activity later in the Return period with the SR Sun in the 3rd House) which elevated him dramatically (Mars in the 10th) and gave him tons and tons of work, responsibility and authority (Saturn on the Ascendant).
The SR Chart for Sept 08 to Sept 09, though, had 29 Aries now having moved from the MC to the Ascendant with the ruler Mars on the Descendant, Saturn now in the 6th along with the Sun (though not conjunct) as well as Mercury and the Moon and Jupiter conjunct the MC. This Saturn was also in opposition to Uranus in the 11th.
As Tr Jupiter moved through the 10th House and squared SR Mars and Tr Mars squared SR Uranus, he was suddenly let go from the job he had gotten during the earlier Saturn on the Ascendant Return.
Now here we are in the months leading up to a new SR chart and, once again, in the Sept 09 to Sept '10 chart he has Saturn on the Ascendant with Mars in the 10th though the ruler of the MC, Mercury, is conjunct this Saturn along with Venus (in the 12th) and the Sun (in the 1st). I anticipate the months leading up to his birthday -- Sept 30 -- to be a flurry of activity with many of the trigger planets transiting conjunct this Mercury, Saturn and the Ascendant.
As far as Progressions go, he had his SP Moon conjunct his Natal Sun in '06 and now he has this SP Moon approaching his SP Sun for a Progressed New Moon.
As I said, SR are fascinating.
