A coronal hole can bean "open" magnetic field in the corona and(perhaps) inner heliosphere which has a fasterthan average outflow (wind); A region of lowerthan "quiet" ion and electron density in thecorona; or a region of lower peak electrontemperature in the corona than in the "quiet"corona.
enumeration
CoronalMassEjection
A solar event (CME) that involves a burstof plasma ejected into the interplanetarymedium. CME's may be observed remotely relativelynear the sun or in situ in the interplanetarymedium. The latter type of observations areoften referred to as Interplanetary CME's(ICME's).

EITWave
A wave in the corona of the Sun which produceshock waves on the Sun's chromosphere (MoretonWaves). EIT Waves are produced by large solarflare and expand outward at about 1,000 km/s.It usually appears as a slowly moving diffusearc of brightening in H-alpha, and may travelfor several hundred thousand km.

GeomagneticStorm
A magnetospheric disturbance typically definedby variations in the horizontal componentof the Earth's surface magnetic field. Thevariation typically starts with a field enhancementassociated with a solar wind pressure pulseand continues with a field depression associatedwith an enhancement of the diamagnetic magnetosphericring current.

RadioBurst
Emissions of the sun in radio wavelengthsfrom centimeters to dekameters, under bothquiet and disturbed conditions. Radio Burstscan be "Type I" consisting of many short,narrow-band bursts in the metric range (300- 50 MHz).; "Type II" consisting of narrow-bandemission that begins in the meter range (300MHz) and sweeps slowly (tens of minutes) towarddekameter wavelengths (10 MHz).; "Type III"consisting of narrow-band bursts that sweeprapidly (seconds) from decimeter to dekameterwavelengths (500 - 0.5 MHz); and "Type IV"consisting of a smooth continuum of broad-bandbursts primarily in the meter range (300 -30 MHz).
enumeration
SectorBoundaryCrossing
A sector boundary crossing is a transit bya spacecraft across the heliospheric currentsheet separating the dominantly outward (away-from-the-sun)interplanetary magnetic field of one hemisphereof the heliosphere from the dominantly inward(toward-the-sun) polarity of the other hemisphere. Such crossings have multi-day intervals ofopposite IMF dominant polarities on eitherside.

SolarFlare

AdiabaticInvariant
A property of a physical system usually relatedto periodic phenomena that remains constantunder slowly varying conditions.
enumeration
AdiabaticInvariant.BounceMotion
The second adiabatic invariant is associatedwith periodic bounce motion of charged particlestrapped between two magnetic mirrors on amagnetic field line. The second invariant,termed J, is defined by using the integralJ = m ∫ v|| * ds where m is the massof the charged particle, v|| is the particlevelocity along the field line, and ds representselemental arc lengths along the field line.The second adiabatic invariant is conservedas long as changes in the background magneticfield occur at time scales much longer thanthe bounce time of the charged particles.

Venus.Magnetosphere.RingCurrent
One of the major current systems confinedwithin planetary magnetospheres. The ringcurrent circles in the magnetic equatorialplane of magnetospheres. It is generated bythe longitudinal drift of energetic chargedparticles trapped on inner, dipole-like magnetosphericfield lines. At the Earth, the ring currentis carried by 10 to 200 keV charged particlestypically located at L-shells between 3 and6. The ring current is also the primary driverof the Sym H and Dst Indices of magnetic stormactivity at the Earth.

BounceMotion
The second adiabatic invariant is associatedwith periodic bounce motion of charged particlestrapped between two magnetic mirrors on amagnetic field line. The second invariant,termed J, is defined by using the integralJ = m ∫ v|| * ds where m is the massof the charged particle, v|| is the particlevelocity along the field line, and ds representselemental arc lengths along the field line.The second adiabatic invariant is conservedas long as changes in the background magneticfield occur at time scales much longer thanthe bounce time of the charged particles.

DriftMotion
The third invariant for charged particle motionin a dipolar magnetic field is associatedwith drift of its guiding center in the equatorialplane. The conserved quantity, J<sub>2</sub>,is equal to qΦ where q is the particlecharge and Φ is the magnetic flux enclosedwithin the particle drift path.

MagneticMoment
A constant of motion related to the gyromotionof a particle in a magnetic field that iseither static or slowly varying with respectto the gyroperiod. The magnetic moment isusually denoted by using the lower case Greekletter for mu, ?, and can be calculated byusing ? = m u^2/2B where m is the particlemass, u is the velocity of the particle perpendicularto the constant or average magnetic fielddirection, and B is the magnitude of the magneticfield strength.

EquatorialRegion
A region centered on the equator and limitedin latitude by approximately 23 degrees northand south of the equator.
enumeration
Ionosphere
The charged or ionized gases surrounding abody that are nominally bound to the bodyby virtue of the gravitational attraction.
enumeration
Ionosphere.DRegion

enumeration
Ionosphere.ERegion
A layer of ionised gas occurring at 90-150kmabove the ground. One of several layers inthe ionosphere. Also called the The Kennelly-Heavisidelayer.
enumeration
Ionosphere.FRegion
A layer that contains ionized gases at a heightof around 150-800 km above sea level, placingit in the thermosphere. the F region has thehighest concentration of free electrons andions anywhere in the atmosphere. It may bethought of as comprising two layers, the F1-andF2-layers. One of several layers in the ionosphere.Also known as the Appleton layer.
enumeration
Ionosphere.Topside
The region at the upper most areas of theionosphere.
enumeration
Mesosphere
The layer of the atmosphere that extends fromthe Stratosphere to a range of 80 km to 85km, temperature decreasing with height.
enumeration
MidLatitudeRegion
When considering the case of the Earth, themid-latitude region typically refers to twolatitudinal bands, one in the northern hemisphereand the other in the southern hemisphere extendingfrom about 23 degrees to 50 degrees. The conceptof mid-latitude regions does not apply toall bodies in the solar system and differentlatitudinal ranges would apply for each bodycase by case. The mid-latitude regions maybe defined by using either planetographicor magnetic coordinates if the magnetic dipoleis closely aligned with the spin axis of amagnetized body. Ground magnetometers locatedat mid latitude on the Earth are well positionedto measure magnetic storm-time ring currentvariations.
enumeration

The sub-auroral regions maybe defined by using either planetographicor magnetic coordinates if the magnetic dipoleis closely aligned with the spin axis of amagnetized body.
