Bureau Home > Radar Images > 128 km Alice Springs Radar Loop. Is a part-time windfinding radar which has routine periods when 'weather watch' coverage.
Rationale: No G1 (Minor) or greater geomagnetic storms are expected. Nosignificant transient or recurrent solar wind features are forecast.
Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-14 over the past 24 hours, wasbelow S-scale storm level thresholds.

---|---|---|---|
S1 or greater | 1% | 1% | 1% |
Rationale: No S1 (Minor) or greater solar radiation storms are expected.No significant active region activity favorable for radiation stormproduction is forecast.
Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.

---|---|---|---|
R1-R2 | 1% | 1% | 1% |

Rationale: No R1 (Minor) or greater radio blackouts are expected. Nosignificant active region flare activity is forecast.
Real Time Images of the Sun
SOHO EIT 304 | SOHO EIT 284 | SDO/HMI Continuum |
The sun is constantly monitored for sun spots and coronal mass ejections. EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin. In those taken at 171 Angstrom, at 1 million degrees. 195 Angstrom images correspond to about 1.5 million Kelvin, 284 Angstrom to 2 million degrees. The hotter the temperature, the higher you look in the solar atmosphere.
Real Time Solar X-ray and Solar Wind
Latest LASCO Solar Corona Large Angle and Spectrometric Coronagraph (LASCO). | Real-Time Solar Wind Real-Time Solar Wind data broadcast from NASA's ACE satellite. |
Solar X-ray Flux This plot shows 3-days of 5-minute solar x-ray flux values measured on the SWPC primary and secondary GOES satellites. | Satellite Environment Plot The Satellite Environment Plot combines satellite and ground-based data to provide an overview of the current geosynchronous satellite environment. |
Solar Cycle
Sun Spot Number Progression This plot shows the Solar Cycle Sun Spot Number Progression. | F10.7cm Radio Flux Progression This plot shows the F10.7cm Radio Flux Progression. |
Ap Progression This plot shows the Solar Cycle Ap Progression. |
The Solar Cycle is observed by counting the frequency and placement of sunspots visible on the Sun. Solar minimum occurred in December, 2008.
Solar maximum was expected to occur in May, 2013.
Solar maximum was expected to occur in May, 2013.
Auroral Activity Extrapolated from NOAA POES
Northern Hemi Auroral Map | Southern Hemi Auroral Map |
Instruments on board the NOAA Polar-orbiting Operational Environmental Satellite (POES) continually monitor the power flux carried by the protons and electrons that produce aurora in the atmosphere. SWPC has developed a technique that uses the power flux observations obtained during a single pass of the satellite over a polar region (which takes about 25 minutes) to estimate the total power deposited in an entire polar region by these auroral particles. The power input estimate is converted to an auroral activity index that ranges from 1 to 10.

GeekWeather is a geeklet for Geektool that shows the DarkSky weather on your desktop. LIGHT is a lighter image for use on darker desktops, DARK is a darker image for use on lighter desktops. LAT and LON are the coordinates of the location you want the weather report for.
Requirements
- WebKit2Png
brew install webkit2png
- ImageMagick
brew install imagemagick
Version
2.0
Tech
GeekWeather uses:
- WebKit2Png: Converts the webpage to a PNG
- ImageMagick: Image convertion
- ForeCast API
Script usage
Example
GeekTool
Run the script via LaunchD or via a script geeklet that returns no output. For LaunchD a plist is included.
- GeekWeather.plist
Drop that into ~/Library/LaunchAgents
Then, point an image geeklet at /tmp/GeekWeather.png
NB__
Webkit2Png uses Python, and on OSX when it runs it'll put an icon in the dock. To suppress the Python icon follow these steps.
