UGEOI

Enables RWC's to send messages containing summaries of daily indices. UGEOI is issued at 0330 UT from RWC BOU.

Example:

Definition of symbols:

First Line-

UGEOI comes from GEOAlert Daily Indices

 

I I I I I = station indicator

 

Y = last digit of year

MM = month of year, 01 = January, 02 = February, etc.

DD = UT day of month

 

HHmm = UT hour and minute of issue

/ = filler

 

dd = UT day of month of data

/// = filler

 

Data Lines-

1 = indicates that relative sunspot number for day dd follows

nnnn = sunspot number

 

2 = indicates that 10.7 cm radio flux for day dd follows

CCC = 10.7 cm radio flux

D = number of TENFLARES (solar radio-emission outbursts at 10 cm that are greater than 100% over background)

 

3 = indicates that Geomagnetic A-index and events observed locally for day dd follows

EEE = Geomagnetic A-index observed

F = important geomagnetic event observed and described as follows:

0 = no event
1 = end of geomagnetic storm
2 = storm in progress
6 = gradual storm commencement
7 = sudden storm commencement

Note: Geomagnetic events and indices are based on local not planetary conditions.

 

4 = indicates that cosmic ray intensity and events observed for day dd by Neutron Monitors follows

GGG = median level of cosmic ray intensity (where 1000 is the normal level)

if GGG > 500, then the median level = GGG
if GGG < 500, then the median level = GGG + 1000
GGG reported as 024 would equal 1024
GGG reported as 892 would equal 892

H = important cosmic-ray event observed and described as follows:

0 = no event
1 = pre-decrease
2 = beginning of a Forbush decrease
3 = Forbush decrease in progress
4 = end of Forbush decrease
5 = arrival of energetic solar particles (GLE)
6 = arrival of energetic solar particles (GLE) followed by Forbush decrease

 

5 = indicates that number of M and X flares for day dd follows

MM = number of M flares

XX = number of X flares

 

6 = indicates that x-ray background (.1-.8 nm) for day dd follows

ab = x-ray background (.1-.8 nm) in units of Wm where ab = a.b

pp = Power of ten to apply to "a.b"

Note: "abpp" reported as "2304" would equal 2.3 x 10 Wm

 

7 = indicates that particle fluence (>10MeV) for day dd follows

ab = particle fluence (>10MeV) in units of particles/cm-sr-day where ab = a.b

pp = Power of ten to apply to "a.b"

Note: "abpp" reported as "4607" would equal 4.6 x 10& particles/cm-sr-day

 

8 = indicates that number of spotted regions and new spot groups for day dd follows

SS = number of new spot groups

NN = number of spotted regions

 

9 = indicates that total sunspot area for day dd follows

AAAA = total sunspot area in millionths of the solar hemisphere

 

Last Data Line-

 

99999 = end of data terminator; indicates that all data has been received

Text Lines-

 

PLAIN = Plain-language text information

 

BT = Break in transmission (end of message terminator)

Note: / is to be used for data not available.
