3241 Yeshuhua represents Jesus Christ (Yeshua) and Christ conciousness, unconditional, endless love, charity, sacrifice in order to help/save others...So maybe it could be used for some aspects of Easter or Christmas.
Halloween is actually the evening before the day of the saints :

Asteroid 522 Helga means holy, blessed :

Today is All Saints Day.
BUT at Halloween - the whole day 24 hours, but specially in the evening -
there are different, creepy beings of the underworld in our realm, they can be clairvoyantly perceived.
I am not yet sure if there were already also saints yesterday, I guess yes, because there were also strong forces from above, I feel for our protection, I think Angels.
I was not able to perceive it absolutely clearly, the impressions from the underworld were overshadowing the sight on lighter beings.
Today I'm sure, the dark beings are gone.
Both asteroids work, I saw it in birth charts and transits, returns...
I didn't try Helga for these two days yet though.
I'll think about asteroids for those creepy creatures...so Halloween.
