ASTRONOMICAL UNIT (AU) The mean earth-sun distance, equal to 1.496E+13cm
or 214.94 solar radii.
| |
AURORA A faint visual phenomenon associated with geomagnetic activity,
which occurs mainly in the high-latitude night sky; typical
auroras are 100 to 250 km above the ground.
| |
AURORAL OVAL An oval band around each geomagnetic pole which is the locus
of structured AURORAe.
| |
AUTUMNAL EQUINOX The equinox that occurs in September.

BRIGHT SURGE ON THE DISK (BSD) A bright gaseous stream (SURGE) emanating
from the CHROMOSPHERE.
| |
BRIGHT SURGE ON THE LIMB (BSL) A large gaseous stream (SURGE) that moves
outward more than 0.15 solar radius above the LIMB.
| |
BURST A transient enhancement of the solar RADIO EMISSION, usually
associated with an ACTIVE REGION or FLARE.
| |
C |
---|
CARRINGTON LONGITUDE A system of fixed longitudes rotating with the sun.
| |
CENTIMETER BURST A solar radio burst in the centimeter wavelength range.
| |
CENTRAL MERIDIAN PASSAGE (CMP) The passage of an ACTIVE REGION or other
feature across the longitude meridian that passes through the
apparent center of the solar DISK.
| |
CHROMOSPHERE The layer of the solar atmosphere above the PHOTOSPHERE and
beneath the transition region and the CORONA.
| |
CHROMOSPHERIC EVENTS Some flares are just Chromospheric Events
without Centimetric Bursts or Ionospheric
Effects. (SID) (Class C flare)
| |
COMPREHENSIVE FLARE INDEX (CFI) The indicative of solar flare importance
given by the sum of the following five components
a) Importance of ionizing radiation as indicated by time-
associated Short Wave Fade or Sudden Ionospheric Disturbance;
(Scale 0-3)
b) Importance of H-Alpha flare; (Scale 0-3)
c) Magnitude of 10cm flux; (Characteristic of log of flux in units
of 10**-22Watt/m**2/Hz)
d) Dynamic spectrum; (Type II = 1, Continuum = 2, Type IV with
duration > 10 minutes = 3)
e) Magnitude of 200MHz flux; (Characteristic of log of flux in
units of 10**-22Watt/m**2/Hz)

CONJUGATE POINTS Two points on the earth's surface, at opposite ends of a
geomagnetic field line.
