For Today...

DESCRIPTION:
The first line is the filename.
The second line indicates the date/time the list was created.
The third line contains the date of the data. Each file (list) contains one UTC day.
Lines that begin with # are header lines.


Event - This is an arbitrary event number assigned by SWPC. It groups several
reports into a single event, as determined by the SWPC forecaster.
+ - A plus sign (+) after the event number indicates that more than one
report was received for this event, and the forecaster has selected
this report to represent those received.

Begin, Max, End -
The UTC Time (Coordinate Universal Time, same as UT) of the beginning,
maximum, and end of the event as reported by the observing site.
"////" indicates a missing time.
The UTC day of the event's begin time is the UTC day of the list.
The UTC day of the maximum and/or end times may or may not be the same
as the begin time. Most solar events are several hours in duration. If
the maximum or end time is less than the begin time, then assume the
times are for the next UTC day. A single letter can proceed a Begin, Max,
or End time. A=after, B=before, U=uncertain. For example the begin time
A0146 means the event began after 0146.

The begin time of an x-ray event is defined as the first minute, in a
sequence of 4 minutes, of steep monotonic increase in 0.1-0.8 nm flux.
The x-ray event maximum is taken as the minute of the peak x-ray flux.
The end time is the time when the flux level decays to a point halfway
between the maximum flux and the pre-flare background level.

The begin time of an SXI flare (XFL) is minutes following the associated
x-ray event. The maximum time is the most intense period in the brightest
region of the SXI image. The end time is the last SXI image before the X-ray
event end time.

Obs - The reporting observatory.
CUL - Culgoora, Australia
HOL - Holloman AFB, NM, USA LEA - Learmonth, Australia
PAL - Palahua, HI, USA RAM - Ramey AFB, PR, USA
SAG - Sagamore Hill, MA, USA SVI - San Vito, Italy
Events from GOES satellites data show the SWPC Primary or Secondary
GOES spacecraft for the observatory, e.g. G12

(See the "Station Lists" directory in the "Welcome" directory for
more information.)

Q - Quality
For radio bursts at fixed and sweep frequencies, and for storms, this
shows the quality of the data
C = Corrected report
G = Good
U = Uncertain
For optical flares, this shows the quality of observing conditions,
from 1 to 5, where: 1 = very poor and 5 = excellent

X-ray events and SXI flare have a quality of 5 (meaning excellent).

Type - Type of report, see www.swpc.noaa.gov/info/glossary.html
BSL = Bright surge on the limb
DSF = Filament disappearance
EPL = Eruptive prominence on the limb
FIL = Filament
FLA = Optical flare observed in H-alpha
FOR = Forbush decrease (cosmic ray decrease))
GLE = Ground-level event (cosmic ray increase)
LPS = Loop prominence system
PCA = Polar cap absorption
RBR = Fixed-frequency radio burst
RNS = Radio Noise Storm
RSP = Sweep-frequency radio burst
SPY = Spray
XFL = SXI X-ray flare from GOES Solar X-ray Imager (SXI)
XRA = X-ray event from SWPC's Primary or Secondary GOES spacecraft

Loc/Frq - Location or frequency.
Location is in degrees latitude, north or south, and degrees longitude,
east or west, from central meridian. The location is the spherical,
heliographic coordinates of the solar region, as a distance in degrees
from a line extending from the solar equator (heliographic latitude),
and distance in degrees from a line extending from the north solar
rotational pole to the south solar rotational pole through the center
of the solar disk, as viewed from Earth (central meridian) in H-alpha.

Frequencies are in Mhz.

Particulars - Additional information from the report, chosen on the basis of
the report type.


XRA: X-ray Class
Class x = peak flux in the 0.1 to 0.8 nm range
In mks system In cgs system
Wm-2 erg cm-2 s-1
A x < 10-7 x < 10-4
B 10-7 <= x < 10-6 10-4 <= x < 10-3
C 10-6 <= x < 10-5 10-3 <= x < 10-2
M 10-5 <= x < 10-4 10-2 <= x < 10-1
X 10-4 <= x 10-1 <= x

Integrated flux from start to end, in joules m E-2.

FLA: Importance and brightness
Importance is the corrected area of the flare in heliospheric
square degrees at maximum brightness, observed in the H-alpha
line (656.3 nm).
S - Subflare (area < or =2.0 square degrees).
1 - Importance 1 ( 2.1 <= area <= 5.1 square degrees)
2 - Importance 2 ( 5.2 <= area <= 12.4 square degrees)
3 - Importance 3 (12.5 <= area <= 24.7 square degrees)
4 - Importance 4 ( area >= 24.8 square degrees)

Brightness is the relative maximum brightness of flare in H-alpha.
F - faint N - normal B - brilliant

Flare Characteristics

VWL = Visible in white light
UMB = Greater than or equal to 20 percent umbral coverage
PRB = Parallel ribbon
LPS = Associated Loop Prominence (LPS)
YSR = Y-shaped ribbon
ERU = Several eruptive centers
BPT = One or more brilliant points
HSS = Associated high speed dark or bright surge
DSD = Dark surge on the disk
DSF = Flare followed the disappearance of a solar filament in the
same region
BLU = H-alpha emission greater in the blue wing than in the red wing

XFL: maximum area (e.g., 1.6e+03) and max intensity (e.g., 1.5e+05).

RBR:
The peak value above pre-burst background of associated radio bursts
at frequencies 245, 410, 610, 1415, 2695, 4995, 8800 and 15400 MHz:
1 flux unit = 10-22 Wm-2 Hz-1

RSP:
The intensity is a relative scale from 1 (low) to 3 (high) of
any sweep radio event associated with the energetic event, as follows

Type II: Slow drift burst
Type III: Fast drift burst
Type IV: Broadband smooth continuum burst
Type V: Brief continuum burst, generally associated with Type III bursts
Type CTM: Broadband, long-lived, dekametric continuum

Shock speed in km/s


Reg# - The SWPC-assigned solar region number. The daily SWPC Solar Region
Summary report contains detailed information about solar regions.
see swpc.noaa.gov/ftpmenu/forecasts/SRS.html

For optical events, region numbers are assigned by the observatory.
Region numbers are assigned to X-ray events by SWPC staff.

For SXI flares, an SWPC algorithm finds the brightest area in the SXI
image and assigns the region number of the closest active solar region.
A region number is assigned to off-disk, west limb events if the region
recently rotated around the limb.
