Fogging
Mars in Leo is currently opposite Neptune in Aquarius (exact yesterday). This could feel a little bit like trying to fight with a cloud, or maybe trying to have sex with one like Ixion, who is currently on the Great Attractor opposite Mercury. This aspect reminds me of the assertiveness technique known as fogging.
Neptune, however, gets occulted by the Moon tomorrow morning at 8:06 UT. It can be interesting when one side of an opposition is occulted, it can sometimes upset the balance, allowing the other side to “win.” In Neptune’s case I doubt it though, he’s more likely to simply go from ephemeral to invisible and back again; hiding suits him fine. If your Mars feels frustrated the next day or so, it’s probably worth consciously putting your passion and energy into something very tangible and present, like yourself (Mars in Leo). The opposition will soon pass.
