  • Sunspots are solar magnetic storms. The spots appear darker because the temperature of the spots are lower than the surrounding photosphere.
  • They serve as a reservoir for solar flares and coronal mass ejections, which cause Aurorae, power/communication outages, and satellite anomalies.
  • The Sun's activity waxes and wanes in an 11-year sunspot cycle; Solar Minimum is when the number of sunspots are lowest.
  • There seems to be a correlation between Solar Min/Maximum and Earth's weather. The extent to which Ozone, stratospheric winds, global circulation patterns, and cloud seeding are all affected are still being studied.

Solar Storms

Solar Radiation Solar Radiation Storms: The Proton Flux shows the last 3 days of data for the most dangerous part of a Solar Storm; Solar Radiation.

Note the left side Particles value of 101 through 105 MeV for the red band, and the duration of the storm. Match with the
Solar Radiation Storm column in the scale.
Solar Storm Index Radio Blackouts: This plot shows the last 3 days of Solar X-ray values for the part of Solar Storms causing radio blackouts.

Note the left side (W/m2) of 10-5 through 10-2 and note the right side M or X. Match with Radio Blackouts column in the
scale.  Affected Freqs

eg. An Xray Flux of 10-3 in the X20 range (very top plot w/out a value in the right side) is indicative of an EXTREME (R5) event-radio blackout on the entire sunlit side of Earth lasting for a number of hours.

Geomagnetic Storm Index Geomagnetic Storms This plot shows Geomagnetic Storm strength. Note the left side Kp value of 5 through 9 (<5 not an event) and duration. Match with the Geomagnetic Storm column in the scale.

eg. A Kp 7 event is a STRONG (G3) event-HF radio may be intermittent, and aurora have been seen as low as Illinois and Oregon.
Direction, Angle, and Magnitude of the Solar Wind can be determined using the dials below.

This plot shows the current extent and position of the auroral oval in the northern hemisphere, during the most recent NOAA POES satellite pass.

The red arrow in the plot, that looks like a clock hand, points toward the noon meridian.

The power fluxes are color coded on a scale from 0 to 10 ergs .cm-2.sec-1 according to the color bar on the right. The pattern has been oriented with respect to the underlying geographic map using the current UTC time, updated every ten minutes.


The Truth About 2012: Solar Storms

Should we be concerned about solar storms in 2012? Heliophysicist Alex Young from NASA Goddard Space Flight Center sorts out truth from fiction.

About the Solar X-ray status monitor

The X-ray Solar status monitor downloads data periodically from the NOAA Space Environment Center FTP server. The previous 24 hours of 5 minute Long-wavelength X-ray data from each satellite (GOES 8 and GOES 10) is analyzed, and an appropriate level of activity for the past 24 hours is assigned as follows:

Status
Normal: Solar X-ray flux is quiet (< 1.00e-6 W/m^2)

Status
Active: Solar X-ray flux is active (>= 1.00e-6 W/m^2)

Status
M Class Flare: An M Class flare has occurred (X-ray flux >= 1.00e-5 W/m^2)

Status
X Class Flare: An X Class flare has occurred (X-ray flux >= 1.00e-4 W/m^2)

Status
Mega Flare: An unprecedented X-ray event has occurred (X-ray flux >= 1.00e-3 W/m^2)
The designation "Mega Flare" was chosen by Kevin Loch when the status monitor was created on March 4, 1999.
There is no "official" designation for flares in this range.


About the Geomagnetic Field status monitor

The Geomagnetic Field status monitor downloads data periodically from the NOAA Space Environment Center FTP server. The previous 24 hours of 3 hour Planetary Kp Index data is analyzed and an appropriate level of activity for the past 24 hours is assigned as follows:

Status
Quiet: the Geomagnetic Field is quiet (Kp < 4)

Status
Active: the Geomagnetic Field has been unsettled (Kp=4)

Status
Storm: A Geomagnetic Storm has occurred (Kp>4)
