| 15-18UT | 1.67 | 1.33 | 2.67 |
| 18-21UT | 1.67 | 1.67 | 3.67 |
| 21-00UT | 1.67 | 1.67 | 3.33 |
Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No significant transient or recurrent solar wind features are forecast.
Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-16 over the past 24 hours, was below S-scale storm level thresholds.
| Mar 28 | Mar 29 | Mar 30 | |
|---|---|---|---|
| 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 storm production is forecast.
Radio Blackout Activity and Forecast
No radio blackouts were observed over the past 24 hours.
| Mar 28 | Mar 29 | Mar 30 | |
|---|---|---|---|
| R1-R2 | 10% | 10% | 10% |
| R3 or greater | 1% | 1% | 1% |
Rationale: There is a slight chance for R1-R2 (Minor-Moderate) radio blackouts all three days.

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.

| Move your cursor over the timeline to 'scrub' through the forecast. |
WSA-Enlil is a large-scale, physics-based prediction model of the heliosphere, used by the Space Weather Forecast Office to provide 1-4 day advance warning of solar wind structures and Earth-directed coronal mass ejections (CMEs) that cause geomagnetic storms. Solar disturbances have long been known to disrupt communications, wreak havoc with geomagnetic systems, and to pose dangers for satellite operations.
Australian Aurora Alert - Detail - Aurora Alert
| Aurora Alerts are issued whenever the Australian region estimated K-index reaches 6 or greater. When an alert is current the alert information indicates the latitudinal range in terms of high, middle, low and equatorial regions where aurora may be visible under good observing conditions. |
Australian Aurora Watch - Detail - Aurora Watch
| Aurora Watches are warnings with lead times of up to 48 hours. They will only be issued in response to a significant solar Coronal Mass Ejection (CME) or coronal hole likely to be geo-effective. Aurora alerts will follow if favourable space weather activity acutally occurs. |
Australian Aurora Outlook - Detail - Aurora Outlook
| Aurora Outlooks are warnings with lead times of 3-7 days. They will be issued in response to the presence of a large active solar region expected to rotate into a position that is favourable for CMEs, and similarly for significant coronal holes. Solar regions that maintain high levels of solar flare activity for sustained periods are rare. Consequently, these notices are likely to be infrequent. Aurora watches and/or alerts will follow if a geoeffective CME is observed and/or significant geomagnetic activity actually occurs. |
Australian Geomagnetic Warning - Detail - Geomagnetic Warning
| Geomagnetic Warnings are issued whenever expected increased levels of geomagnetic activity are current. |
Australian Geomagnetic Alert - Detail - Geomagnetic Alert
| Geomagnetic Alerts are issued whenever the Australian region estimated K-index reaches 5 or greater. |
Australian Region K-index - Detail - Current Estimated Aus K-index
| K index is a measure of geomagnetic activity for a 3-hour period. The larger the K index, the greater the chance of seeing an aurora at lower latitudes. To check if an aurora could be visible at your latitude for a given K-index value, look at the table of visibility range estimates or try out the Auroral Oval Prediction Tool. The Kaus index is the Estimated Australian Region K index sourced from SWS. Kaus is a near real-time estimate of the K index for the Australian region, which is recalculated approximately every 5 minutes. The Kp index is the Estimated Planetary K index sourced from NOAA/SWPC. The Kp index is updated every 3-hours and its timestamp will be behind that of the Kaus index. Estimated K-indices generated for the Australian region are the average of the estimated K-indices from the individual stations and have a range of values from 0 (very quiet) up to 9 (extremely disturbed). |

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.
