Meteors: An Unexpected Increase in 1963.
Counts of meteors observed by radar from Christchurch, New Zealand, rose unexpectedly by over 100 percent during mid-1963. A similar but smaller increase was also observed in Canada. Diminishing peaks have subsequently appeared at 6-month intervals in the Christchurch meteor counts.
