This product is based on the OVATION model and provides a 30 to 90 minute forecast of the location and intensity of the aurora. Re: Aurora Australis in July? In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin. The K index is a measure of geomagnetic activity for a 3-hour period. Here some of the best places to see the aurora are in locations far away from major sources of light pollution, where the night sky is clear and undisturbed.

By adding data from the NASA TIMEDGUVIinstrument, Newell et al., were able to expand the model to include the larger storm values of Kp of 8 and 9. Auroras are generally fickle creatures that do not show themselves to everyone, and I certainly wouldnt advise anyone to visit Tasmania just to see one, he says. 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. The risk for mosquito activity are extremely high. Tip #2: Be at your designated viewing spot by midnight. Res., 114, A09207,doi: Machol, J. L., Green., J. C.,Redmon, R. J.,Viereck, R. A., Newell, P.

The Aurora might be visible at 45 degrees, 30 degrees or even lower on the horizon depending on its brightness. 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. Because the view-line images are based on forecast Kp, the images themselves are not archived. The brightest displays typically last for about 1-3 hours, and the best viewing times are generally between 10 pm and 2 am. . In those instances, an alternative estimate of the solar wind forcing, based on the current Kp geomagnetic index is used to drive the OVATION model. Another relatively good season for aurora borealis in Tasmania is in winter, roughly from May to August.

Stay hydrated to make the most of your ride. According to Dr Parkinson, Tasmanias unique location means that auroras can actually be seen at this phase of the solar cycle as often as every week although most people would not naturally recognise the phenomenon when it is low to the horizon. of Commerce, NOAA, Space Weather Prediction Center. The brightness and location of the aurora is typically shown as a green oval centered on Earths magnetic pole. . The mounting probability of aurora sightings has helped to lift interest in the recent launch of the Bureaus online Aurora Patrol Cameraa sophisticated all-sky camera located near Cressy in Tasmania, which enables members of the public to monitor the sky in real time. al., developed the OVATION model. For instance, if there is strong aurora australis activity over the Southern Ocean, several hundreds of kilometers away from the Australasian landmass, you still see it from the shore.

Fresh and gusty northwesterly winds, shifting southwesterly during the morning before easing late. Experienced observers recommend planning the trip for September when the southern lights are most vivid. The risk of dust and dander allergy symptoms is very high. Snow to 900 metres about the west late. This version has been dubbed OVATION 2020. Wind Gusts 7 mph. 1. The larger the K index, the greater the chance of seeing an aurora at lower latitudes. Alerts, Watches and Warnings. The brightest auroras are concentrated in a ring the auroral oval centred on the Earths magnetic pole. Search for the Southern Cross constellation. In those taken at 171 Angstrom, at 1 million degrees. The power input estimate is converted to an auroral activity index that ranges from 1 to 10. Conditions for outdoor entertaining will be good. (Weather station: Launceston Airport, Australia). In 2016, NOAASWPCshared the operational OVATION code (written inIDL) with the UK Met Office in the UK. Located relatively close to the South Pole, Tasmania is a perfect spot for observing the fascinating natural phenomenon of the aurora australis. :Product: 3-Day Forecast :Issued: 2023 Jul 12 0030 UTC # Prepared by the U.S. Dept. The Tasmanian aurora spectacle is somewhat elusive so we can never be sure when the solar winds will make it shine the brightest. 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. Weather permitting, active auroral displays will be visible overhead from Utqiavik to Anchorage and Juneau, and visible low on the horizon from King Salmon and Prince Rupert. Be sure to wear sunscreen and UV-protective clothing when spending time outdoors. The emergence of colors and flickers in the night starry sky creates an impression of the universe close at hand. Conditions for hiking are good. proximity or glancing blow CME from 15 Jul. Winds west to northwesterly 15 to 25 km/h. hours. With the Earth emerging from its solar maximum, the peak of its 11-year solar weather cycle, it is likely to see increases in the geomagnetic activity and solar winds that form aurorasknown as australis in the southern hemisphere, and borealis in the northern. Alternating mowing patterns can help all areas of your lawn grow. The optimal time to catch the southern lights in Tasmania is from May to August.

The Aurora Australis Tasmania Facebook group has an active community of more than 100,000 people, while the Aurora Australis Tasmania Alert NOW page delivers on-the-spot reports of aurora sightings. Most are generated automatically, with only limited quality checks performed. The Bureau also provides a free aurora alert service, which sends out an email (or paid SMS messages) to subscribers to help them identify locations and times that are expected to be conducive to auroras. Higher altitude areas of the country may also see the aurora on the horizon. The OVATION (Oval Variation, Assessment, Tracking, Intensity, and OnlineNowcasting) model is an empirical model of the intensity of the aurora developed at the Johns Hopkins University, Applied Physics Laboratory by Patrick Newell and co-workers[1]. Tip #1: The winter months provide perfect conditions. Typically, the images of polar lights present an array of dazzling colors. When chasing auroras, you want to check the geophysical data for an area slightly further south of your viewing spot. 6 years ago Save No, of you're only reason for going is in the belief you will see the "lights" then don't go. These observations have not been quality controlled. You ideally need a dark night with very little cloud, no bright moon, and no light pollutionpreferably on a dark beach or headland. An estimate of aurora viewing probability can be derived by assuming a linear relationship to the intensity of the aurora. The aurora is not visible during daylight hours. Best places to see the southern lights in New . For the best shots, you will need to hike to South Cape Bay. Showers developing about the west around the middle of the day, then extending to the remainder of the north during the afternoon. There is a very slim chance of this.

Taking a hot shower may help ease sinus pressure. Provides access to Tasmanian weather forecasts, weather observations, flood warnings and high sea forecasts of the Bureau of Meteorology and Tasmanian - Antarctica Regional Office National Oceanic and Atmospheric Administration. The sun is constantly monitored for sun spots and coronal mass ejections. The risk of grass pollen symptoms is low. Home Aurora Related Sites Cloud Cover Sunday, Jul 16 2023 10:06 UT. Medium chance of showers, most likely in the afternoon and evening. The model uses the solar wind velocity and interplanetary magnetic field measured at the L1 orbit position at 1.6 million km (1 million miles) upstream from earth as input and calculates three types of electron precipitation and the proton precipitation which strongly correlate with the aurora. Wind E 7 mph. These links provide a discussion of the aurora phenomena and tips for the best opportunities to view aurora at various locations around the world. At this time of year, nights are longer, giving more opportunities to spot the southern lights. A short term forecast (~30 minutes) along with the last 24 hours of activity can be found on theAurora - 30 Minute Forecastpage. The green ovals turn red when the aurora is forecasted to be more intense.
