Appleton et a/.1 first studied sporadic-E in the auroral zone and found frequent occurrence of E. on disturbed days as compared to the quiet days. Smith' found similar results for auroral zone butAuthor: R C Saksena, E S Owen-Jones.
The wind‐shear theory is most likely to explain temperate‐zone sporadic E. In the equatorial zone, VHF reflections are most probably due to the two‐stream plasma instability, though gradient instabilities may play a part in producing the irregularities that cause HF vertical‐incidence reflection.
These results may be used to determine short and long-term movements of the sporadic E auroral zone. It is found sporadic E auroral zone. book the sporadic E auroral zone moves from nighttime to daytime, from winter to summer, and from the International Geophysical Year to the International Quiet Sun Year towards the pole.
SHORT PAPER Forecasting auroral sporadic-E with a magnetometerA.D. Morgan, Government Communications Headquarters, Cheltenham, England Government Communications Headquarters Cheltenham Varanasi England Abstract Large disturbances of the Earth's magnetic field outside the auroral zone are often accompanied by intense sporadic-E in the auroral by: 4.
In Fig. 5 we see a series of four contour charts representing longterm averages of the occurrence of sporadic E as observed at stations located in four principal zones (i.e. the north- and south-temperate zones, the equatorial zone, and the north-auroral zone).Cited by: 8.
Furthermore, sporadic E occurrence depends on several geophysical parameters such as dynamic conditions in the lower thermosphere, intensity of Earth’s magnetic field and meteor flux.

We have built up an extensive range of trusted and knowledgeable Aurora guides, photographers and experts throughout Northern Scandinavia and combined with our 6-point Aurora hunting plan, we are quite simply your best chance for seeing the Northern Lights.
Sporadic E is a regular daytime occurrence over the equatorial regions and is common in the temperate latitudes in late spring,early summer and, to a lesser degree, in early winter. At high, i.e., polar, latitudes, Sporadic E can accompany Auroras and associated disturbed magnetic conditions.
Etymology. The word "aurora" is derived from the name of the Roman goddess of the dawn, Aurora, who travelled from east to west announcing the coming of the t Greek poets used the name metaphorically to refer to dawn, often mentioning its play of colours across the otherwise dark sky (e.g., "rosy-fingered dawn").Occurrence.
Most auroras occur in a band known as the "auroral zone. The first is an auroral E,-layer and/or retarded type sporadic E-band that has previously (Whalen et al., ) been found to be identical with the continuous aurora.
Ionospheric sporadic-E (Es) activity and global morphology were studied using the 50 Hz signal-to-noise ratio amplitude and excess phase measurements from the FormoSat-3/Constellation Observing System for Meteorology, Ionosphere and Climate (FS3/COSMIC) GPS radio occultation (RO) observations.
The results are presented for data collected during the last sunspot cycle from mid Cited by: 2. Bernt Maehlum has written: 'The sporadic E auroral zone' -- subject(s): Auroras, Sporadic E (Ionosphere) 'Small scale structure and drift in the sporadic E layer as observed in the auroral zone.

(Field-Aligned Irregularities) Sporadic E Explained - Sporadic E is a form of propagation that can arise with little warning, and enable radio frequencies of MHz and more to travel over distances of a thousand kilometres and more.
Finnish Lapland is home toreindeer,people, 6 national parks but more importantly, it is possible to witness Auroral activity on anything up to nights per year!.
There is a reason why we offer more Northern Lights Holidays to Finland than we do anywhere else in the world and that reason is years and years of Aurora hunting experience.
Sporadic E, or Es is a mode of radio propagation that occurs on occasions. As the name indicates, sporadic E is not easy to predict. It occurs on an occasional basis, and can affect radio communication on frequencies from a few MHz up to those much higher than would normally be expected.

Sporadic E, also known as Es (i.e. E sporadic) is a form of E layer ionisation that occurs randomly in the ionosphere. It can affect frequencies normally affected by ionospheric propagation, but as the levels of ionisation can rise very high, it can affect frequencies much higher than would be expected by normal E region ionisation.
The images revealed that "there are different kinds of irregularities in the auroral zone compared to the polar cap," according to coauthor Anthony Mannucci, such that "the effects on radio signals will be different in these two locations." Specifically, the disturbances in the auroral region were larger in scale (about kilometers in diameter) than those over the Arctic polar cap (about 1.

• Adam Roberts’ latest book is Bête (Gollancz). The map shows the intensity and the location of the auroral oval for the time given in the right-hand corner of the map. Locations up to kilometers ( miles) north or south of the auroral oval might still see aurora near their horizon during optimal viewing conditions.
