PLAIN
This message is for users of the NOAA/SEC Space
Weather Operations sunspot region numbers. As you
may have noticed, we are steadily approaching
region number 10000. The plan for Space Weather
operations is to go 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 regions numbers 10000 and higher.
