 We have performed a study of two associated upward lightning flashes that involved two adjoining tall grounded objects with a time difference of about 45.8 ms. These two associated lightning are found to have opposite polarity, the first one being negative and the second one, positive. Their occurrence appears to be direct evidence that one upward lightning flash can trigger other upward lightning of opposite polarity from nearby tall grounded objects.
