Activiteitenrapport
Bij elke genoemde zonnevlam in dit rapport werd een schaalfactor toegepast door het Space Weather Prediction Center (SWPC). Vanwege de SWPC-schaalfactor worden zonnevlammen 42% kleiner gerapporteerd dan voor de wetenschappelijke data. De schaalfactor werd verwijderd uit onze gearchiveerde zonnevlamdata om de werkelijke fysieke eenheden weer te geven.

IA. Analyse van de actieve zonneregio's en zonneactiviteit van 11-2100Z tot 12-2100Z
Solar activity was at low levels. Optically verified
using EIT imagery, Region 9987 (S15W56) produced a C1 x-ray flare at
12/0903 UTC. This region underwent slight decay today. Less
penumbral coverage seen in trailing cluster of spots, although
region continues to exhibit beta-gamma magnetic characteristics.
Region 9991 (S22E04) showed slight growth in penumbral coverage
during the period. Other than occasional point brightening and
minor dark surging, this region was stable through the period. A
Type II radio sweep with an estimated shock velocity of 450 km/s
occurred at 12/0145 UTC. Source region of the sweep is believed to
have originated from beyond the northeast limb of the visible disk.
Regions 9996 (S27E46), 9997 (N08E73), and 9998 (N15E74) were
numbered today.
IB. Voorspelling zonneactiviteit
Solar activity is expected to be at
low levels. Region 9987 remains capable of producing an isolated
low level M-class flare.
IIA. Samenvatting geofysische activiteit 11-2100Z tot 12-2100Z
The geomagnetic field activity was at quiet to unsettled levels.
IIB. Voorspelling geofysische activiteit
The geomagnetic field activity
is expected to continue at quiet to unsettled levels. Day three of
the forecast period may experience isolated active conditions in
response to a southern hemispheric high speed stream coronal hole
becoming favorably positioned.

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.
