Parallel of Declination
The Parallel aspect is formed between two planets with the same declination or distance north or south of the ecliptic. If the planets are both North or both South of the ecliptic, the parallel aspect is read as a conjunction. If they are the same declination but one is North and one is South, then the contra-parallel is read as a 180 degree opposition.
These aspects are strongest when the orb is kept to 1 degree. They can also magnify the intensity of any other aspect between the two planets or points.
