Pluto transit Mean Node?

[Light Yagami]

Hello.
It seems like Pluto will have an interraction with my Mean Node. (a transit)But I have no idea what my Mean Node stands for and what I should be prepared for.
I know Pluto = Pluto is ones intensity and obsessions. (and the rest written on JoS)

But can anyone shed some light here in regards to the Mean Node and what could happen when this transit occurs?Thank you.

also check in what house is that node posited in ?
i dont think the lunar nodes are effected by transits much for personal changes in the life for you,

you need to look at everything , cant tell just from this single aspect...
solar returns
i have mercury conjunct my natal southnode and this ties in with the year 2021 which is fated for me(south node conjunct SR asendant) involving solar return venus and other aspects..
