Request an information pack containing links to the Aurora brochure, case studies, videos and links to each of the cohorts for Aurora Aurora is for those who identify as women, up to senior lecturer level or the professional services equivalent, working in a university, college or related organisation who would like to develop and explore issues relating to leadership roles and responsibilities. Participants should have the endorsement of their institution either their Aurora Champion, Human Resource department or line manager and be committed to developing and enhancing their career.
With cohorts running at a number of locations across the UK and Ireland, the Aurora programme is a mix of face to face development days held in large regional venues, action learning sets and self-directed online learning modules. Participants are guided by role models and supported by mentors from your institution. All bookings on Aurora must be made through or with the permission of your institutions Aurora Champion list found here.
As an Aurora Champion or person who supports Aurora bookings within your institution to book yourself or multiple delegates on to the programme, please book online for each cohort through the links below you will be redirected to Advance HE's MYLF. Institutions are responsible for coordinating Aurora within their organisation, providing mentors for their participants and supporting participants to attend the development days and their action learning sets.
In each institution, Aurora is led by an Aurora champion.

Aurorasaurus - Reporting Auroras from the Ground Up
This gives us a sheltered place to enjoy the evening when the Aurora is not on display and to warm up with hot chocolate, coffee and tea. Following a brief orientation, you can walk around our spacious property to find your perfect aurora viewing location using the Teepee as a base. The Village is sheltered from the subarctic wind by a beautiful forest — with groomed trails leading up to surrounding panorama hills for a secluded and clear viewing of the stunning display from mother nature. Guests will be wowed by the Aurora Borealis dancing overhead and we have everything they need to enjoy the experience….
For people that want that extra comfort you can upgrade to our custom built heated seats. There is a photographer on hand in our Village Gift Shop where we provide tips and tricks for the perfect Aurora photo. If you bring your own camera we also rent tripods. The Gift Shop is stocked with locally harvested goods, crafts, syrups, teas, art and souvenirs we also have an incredible range of Aurora Photography for you to choose from and take home.
Meals are available at the Aurora Village Resturant by day and by night. With A La Carte dining and three-course dining experience, you will love some of the items on our menu. Please be in the lobby of the hotel at least 5 minutes before the scheduled time. Our guides will be waiting in the lobby of the hotel. The distance, or radius, of the electron from the field line at any time is known as its Larmor radius.
The pitch angle increases as the electron travels to a region of greater field strength nearer to the atmosphere. Other particles that do not mirror enter the atmosphere and contribute to the auroral display over a range of altitudes. Other types of auroras have been observed from space, e.
These are relatively infrequent and poorly understood. Other interesting effects occur such as flickering aurora, "black aurora" and subvisual red arcs. In addition to all these, a weak glow often deep red observed around the two polar cusps, the field lines separating the ones that close through the Earth from those that are swept into the tail and close remotely. Images of auroras are significantly more common today than in the past due to the increase in the use of digital cameras that have high enough sensitivities.
Due to the different color spectra present, and the temporal changes occurring during the exposure, the results are somewhat unpredictable. Different layers of the film emulsion respond differently to lower light levels, and choice of a film can be very important. Longer exposures superimpose rapidly changing features, and often blanket the dynamic attribute of a display.
Higher sensitivity creates issues with graininess. David Malin pioneered multiple exposure using multiple filters for astronomical photography, recombining the images in the laboratory to recreate the visual display more accurately. Predictive techniques are also used, to indicate the extent of the display, a highly useful tool for aurora hunters.
Early work on the imaging of the auroras was done in by the University of Saskatchewan using the SCR radar.

Aurora during a geomagnetic storm that was most likely caused by a coronal mass ejection from the Sun on 24 May , taken from the ISS. Auroras frequently appear either as a diffuse glow or as "curtains" that extend approximately in the east-west direction. At some times, they form "quiet arcs"; at others, they evolve and change constantly. These are called "active aurora". The most distinctive and brightest are the curtain-like auroral arcs. Each curtain consists of many parallel rays, each lined up with the local direction of the magnetic field, consistent with auroras being shaped by Earth's magnetic field.
In situ, particle measurements confirm that auroral electrons are guided by the geomagnetic field, and spiral around them while moving toward Earth. The similarity of an auroral display to curtains is often enhanced by folds within the arcs. Arcs can fragment or break up into separate, at times rapidly changing, often rayed features that may fill the whole sky. These are the discrete auroras, which are at times bright enough to read a newspaper by at night. The diffuse aurora, though, is a relatively featureless glow sometimes close to the limit of visibility. Diffuse auroras are often composed of patches whose brightness exhibits regular or near-regular pulsations.
The pulsation period can be typically many seconds, so is not always obvious. Often there are black aurora i. A typical auroral display consists of these forms appearing in the above order throughout the night.
X-ray emissions, originating from the particles associated with auroras, have also been detected. The charged particles discharge when particles from the Sun hit the inversion layer, creating the noise. A full understanding of the physical processes which lead to different types of auroras is still incomplete, but the basic cause involves the interaction of the solar wind with the Earth's magnetosphere.
The varying intensity of the solar wind produces effects of different magnitudes but includes one or more of the following physical scenarios. The details of these phenomena are not fully understood.
However, it is clear that the prime source of auroral particles is the solar wind feeding the magnetosphere, the reservoir containing the radiation zones and temporarily magnetically-trapped particles confined by the geomagnetic field, coupled with particle acceleration processes. The immediate cause of the ionization and excitation of atmospheric constituents leading to auroral emissions was discovered in , when a pioneering rocket flight from Fort Churchill in Canada revealed a flux of electrons entering the atmosphere from above.
Electrons mainly responsible for diffuse and pulsating auroras have, in contrast, a smoothly falling energy distribution, and an angular pitch-angle distribution favouring directions perpendicular to the local magnetic field. Pulsations were discovered to originate at or close to the equatorial crossing point of auroral zone magnetic field lines. Both incoming electrons and protons may be involved. Excitation energy is lost within the atmosphere by the emission of a photon, or by collision with another atom or molecule:.
Oxygen is unusual in terms of its return to ground state: it can take three-quarters of a second to emit green light and up to two minutes to emit red. Collisions with other atoms or molecules absorb the excitation energy and prevent emission. Because the highest atmosphere has a higher percentage of oxygen and is sparsely distributed such collisions are rare enough to allow time for oxygen to emit red.
Collisions become more frequent progressing down into the atmosphere so that red emissions do not have time to happen, and eventually, even green light emissions are prevented. Green is the most common color. Then comes pink, a mixture of light green and red, followed by pure red, then yellow a mixture of red and green , and finally, pure blue.
Bright auroras are generally associated with Birkeland currents Schield et al. The ionosphere is an ohmic conductor , so some consider that such currents require a driving voltage, which an, as yet unspecified, dynamo mechanism can supply. Electric field probes in orbit above the polar cap suggest voltages of the order of 40, volts, rising up to more than , volts during intense magnetic storms.
Ionospheric resistance has a complex nature, and leads to a secondary Hall current flow.
