  We present the sympathetic eruption of a standard and a blowout coronal jets
originating from two adjacent coronal bright points (CBP1 and CBP2) in a polar
coronal hole, using soft X-ray and extreme ultraviolet observations
respectively taken by the Hinode and the Solar Dynamic Observatory. In the
event, a collimated jet with obvious westward lateral motion firstly launched
from CBP1, during which a small bright point appeared around CBP1's east end,
and magnetic flux cancellation was observed within the eruption source region.
Based on these characteristics, we interpret the observed jet as a standard jet
associated with photosperic magnetic flux cancellation. About 15 minutes later,
the westward moving jet spire interacted with CBP2 and resulted in magnetic
reconnection between them, which caused the formation of the second jet above
CBP2 and the appearance of a bright loop system in-between the two CBPs. In
addition, we observed the writhing, kinking, and violent eruption of a small
kink structure close to CBP2's west end but inside the jet-base, which made the
second jet brighter and broader than the first one. These features suggest that
the second jet should be a blowout jet triggered by the magnetic reconnection
between CBP2 and the spire of the first jet. We conclude that the two
successive jets were physically connected to each other rather than a temporal
coincidence, and this observation also suggests that coronal jets can be
triggered by external eruptions or disturbances, besides internal magnetic
activities or magnetohydrodynamic instabilities.
