UGEOI Codes
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 ddfollows
- 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:
- e = optical flare importance based upon corrected area in square degrees
- 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
- 0 = no Type IV sweep observed
- 1 = importance 1
- 2 = importance 2
- 3 = importance 3
- 9 = unknown
- ab = x-ray background (.1-.8 nm) in units of Wm-2 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
- 7 = indicates that particle fluence (>10MeV) for day dd follows
- ab = particle fluence (>10MeV) in units of particles/cm2 -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/cm2-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 Lines-
- 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.
