Researchers at the Air Force Research Laboratory in New Mexico have discovered a new way to track and characterize sporadic E which occurs when large structures of dense plasma form naturally in the upper atmosphereThese plasma structures which occur at mid-latitude locations around the world can affect radio wave propagation in both positive and.

E sporadic map. Four days of Sporadic E and why a superstation would not help me much. Figure 2 Statistical maps of sporadic E show that North American longitudes are less active on average compared to European longitudes. Heres my own crude illustration of a sporadic E cloud.

144MHz sporadic-E from 2001. It uses data gathered by Automatic Packet Reporting System-Internet Service APRS-IS from packet stations in the amateur radio service. Sporadic E arises when very intense clouds of ionisation build in the lower reaches of the E region of the ionosphere.

It covers eastern Europe Western Russia Italy most of the Mediterranean southern Spain Portugal and north Africa. The longitudinal structure in the altitude of the Sporadic E Es was investigated for the first time based on the S4 index provided by the Constellation Observing System for Meteorology Ionosphere and Climate COSMIC in low latitudes. Send formated DX spots indicating clearly both locators and the type or.

VHF Propagation Map This map shows real-time radio propagation from stations operated near 144 MHz. The level of ionisation may be up to five times greater than those normally achieved at the peak of the sunspot cycle and this is the reason why signals well into the VHF region of the radio spectrum can be reflected. The maximum useable frequency of a sporadic E s layer MUF_E_s is about 5319 times the depicted critical frequency f_oE_s Source.

Six meter beacons can help. October 18 2015 Foliage Looking Southwest from Lower Front Deck. 144 MHz Sporadic-E QSO animated maps in Europe.

New Hampshire Foliage Tracker. Obviously Sporadic E is something you cannot count on. Propagation data available in the application as great circle maps and processed data analysis.

Data stored for future analysis Astronomical mapping circular and flat map. Stereo 3D of the Sun 5 MUF MAP. 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.

I will appreciate links to this WEB page but you are not allowed to show the maplist in your site. Plain Language Summary Dense patchy layers of plasma that form in the E layer of the ionosphere sporadic E often reflect high frequency radio waves from distant over-the-horizon sources. Reading MAPPING SPORADIC-E.

Four days of Sporadic E. Not Four Days of Dunkirk which is a cycle race nor Four Days of Ghent which was an important battle in Flanders in 1789. YOU MAY NOT use this maplist in your own WEB pages.

If you are a 10 metre band enthusiast you might get it four days in. You can help generate this page. Please note the RSGB is not responsible for the content of external websites.

While detectable with current radar techniques sporadic E is difficult to image over large regions due to the limited field of view of a typical radar. Plot updated every 15 minutes of the critical frequency f oEs of the sporadic E s layer in the vicinity of where your IP address is thought to be located. 6-Meter Sporadic E Using Amateur Radio to conduct real science in pursuit of a decades-old mystery.

William Hepburns Worldwide Tropospheric Ducting Forecast Site. Paths are smoothed to create a color-coded footprint indicating the distance VHF signals are. LIGHTNING ACTIVITY- Sometimes appears to correlate with Es and often NOT.

The new PARKER Solar Probe CQ DXCan anybody Hear Me Now 3 Sporadic-E Clouds MAP Real Time. Sporadic E s layers are patches of relatively high electron density at a height of in between 90 to 160 km. DX Maps does a great job of showing where the cloud is with the propagation on all sides out to about 1500 miles for single hop.

1 Live Time MUF MAP North American Sporadic-E. QSOSWL real time maps and lists 30 MHz. The links below provide information about Sporadic-E and Spread-F.

Send formatted DX-Spots that can be easily interpreted by DXMAPS. Sporadic E or Es is a mode of radio propagation that occurs on occasions.

This link is listed in our web site directory since Friday May 29 2015 and till today Sporadic-E DX Map has been followed for a total of 457 timesSo far no one has rated yet so be the first to rate this link. As the name indicates sporadic E is not easy to predict. This helps to make short term predictions of possibilities.

The map shows activity from the past hour. Live Sporadic-E Map Europe and Transatlantic 30MHz from G7IZU. November 2015 Same shot a month later with front yard cleaned up.

Now you can also receive customized propagation alerts by E-Mail. However what is characteristic of sporadic-E propagation is the strength of the signals particularly over the shorter distances. The longitudinal structure is identified as a symmetrically located wavenumber-4 WN4 pattern within 30S30N.

They should not be taken as an exact reference as I have missed many openings in those years. Cycle 24 Radio Secrets. Sporadic-e Propagation at VHF.

The key of course is determining when the cloud appears and getting everyone on the air who are in the right places to make QSOs. More about Sporadic E. Live propagation analysis inc.

This statistics were made using the data of the sporadic-E openings worked by myself from Jan1987 to Dec2002. FOXTROT LIMA Latest DX Spots. The map below illustrates the area workable from central England via sporadic-E.

The patches of sporadic E s are in fact clouds of ionised metal atoms from disintegrated. You can help in the development of these maps and in other VHF propagation analysis projects. Sporadic E s blanketing mainly in summer.

SkyNet TEST PAGE. Adapted from Arras et al 20101 Figure 1 Typical European sporadic E in August 2016. Sporadic e F layer field aligned tropo and aurora.

The presence of a transient fairly local sporadic E s layer is a relatively common phenomenon.
