No bulletins were produced for the period October 1976 through September 1977. On 1. October 1976, the array was reduced from 22 to 7 subarrays, and during the first year of operating the smaller array, NORSAR produced no bulletins. Furthermore, no bulletins were produced for the months Sep/Oct/Nov 1995 as the array was down for refurbishment (replacement of old electronics and seismometers).
