Spark

Excerpted from If your MagSafe cable or power adapter isn't working - Apple Support:

If you see a spark

Sometimes when you plug the power adapter into the wall, you may see a spark. This is usually normal and can occur when you plug any electrical appliance into a live outlet. If the spark comes from somewhere other than the blades of the plug, if you experience any damage or discoloration of the adapter, or if you have other concerns about sparking, contact Apple.

leroydouglas has the best advice -- if no issues, ignore it.

Plugging devices into AC wall power often causes a spark, but in most cases, we do not see those sparks.
