Transits to natal and SSR, using all multiples of 45°, have long been established as a baseline of predictive work, exactly with the orb you indicated. The other aspect types are more suspicious... but the actual looking you are doing is the key to learning these things. (Your remarks on Demi-Solar are interesting, I've probably never even looked at this and might add a few spot checks of key planets like Moon next month.)
One piece of advice on aspects like this example: Most of the time, transits to slow planets in the Lunar Return will mean the same aspect to current transits. In other words, transiting Venus trine SLR Jupiter-Neptune recently probably occurred on a day that transiting Venus, transiting Jupiter, and transiting Neptune were all in aspect in space, affecting everybody and not unique to your chart. These are still valid aspects, of course - and notice that the event you described wasn't an individual event but a mass, collective event. I suggest that the world was experiencing Venus-Jupiter-Neptune, and it marked this concert.coolcoolwcr wrote: Tue Jun 05, 2018 11:56 pm Transit venus in trine aspect to lunar return jupiter-neptune trine, forming a grand triangle in return map : attending a great concert, everyone there seems to be in a state of emotional excitement, as befits the symbolizm of Neptune
I mention this because the phenomenon might lead you to wrong conclusions. I'm intrigued by what you say about transits to the SLR because, over the years, I haven't even been able to determine that transits to SLR angles have any value (some astrologers like to use that as timing within the month; I just don't see it). It's possible I missed something, or possible that you are mostly noticing transit-to-transit aspects that just happen to be to SLR planets, too.
This would also explain the trine. Generally, transiting trines and sextiles don't work (or their effect is so subtle that one might as well say they don't work). They don't move anything to happen. But transit-to-transit trines and sextiles are quite effective.
