Comments: PLAIN This message is for users of the NOAA/SEC Space Weather Operations sunspot region numbers. As you may have noticed, region number 10000 was assigned on June 14. Space Weather operations is going through the sequence of Region numbers as 9998, 9999, 0000, 0001, and so on. SEC's product text discussions of the active regions will ignore the leading zeroes (for example, we will say 'Region number 5' rather than Region number '0005'). However, the Geoalert product, the Region Report product, as well as the USAF and IUWDS data exchange codes will preserve the 4 digit format. The necessity of using four digits is for operational purposes only. For historical purposes all regions beyond Region 9999 will be understood to be in a series of region numbers 10000 and higher. 99999
