The intensity of the storm brought the visibility of the aurora to lower latitudes, and it was reportedly seen in places such as Florida and the Caribbean. Ionospheric storms can happen at any time and location. [6] F-region and D-region ionospheric storms are also considered main categories of ionospheric storms. The F-region storms occur due ...
A deviated septum is an abnormal condition in which the top of the cartilaginous ridge leans to the left or the right, causing obstruction of the affected nasal passage. It is common for nasal septa to depart from the exact centerline; the septum is only considered deviated if the shift is substantial or causes problems. [3]
Solar storm of Oct-Nov 1903 An extreme storm, estimated at Dst −531 nT arose from a fast CME (mean ≈1500 km/s), occurred during the ascending phase of the minimum of the relatively weak solar cycle 14, which is the most significant storm on record in a solar minimum period. Aurora was conservatively observed to ≈44.1° ILAT, and ...
The ionospheric disturbance enhances VLF radio propagation. Scientists on the ground can use this enhancement to detect solar flares; by monitoring the signal strength of a distant VLF transmitter, sudden ionospheric disturbances (SIDs) are recorded and indicate when solar flares have taken place.

Indicates that the air below the cloud is dry; can also signify the downdraft region of a storm. Wall clouds A supercell forms and a wall cloud pushes north of Beardstown, Ill. Friday, March 31 ...
A septoplasty is a surgical option that a doctor may recommend for treating a nasal blockage, such as a deviated septum. Also known as septal surgery, the procedure typically involves ...
The study of these disturbed volumes yields important information for understanding natural ionospheric processes. During active ionospheric research, the signal generated by the transmitter system is delivered to the antenna array and transmitted in an upward direction. At an altitude between 70 and 350 km (43 and 217 mi) (depending on ...
Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere.
