![]() September and October will be warmer and drier than normal. The hottest periods will be in mid-June and early and late July. Rainfall will be near normal in the north and above normal in the south. Summer temperatures will be slightly below normal along the coast and hotter than normal inland. April and May will be slightly warmer than normal, with rainfall near normal in the north and below normal in the south. The stormiest periods will be in mid- to late December, early and late January, early and late February, and late March. The coldest temperatures will occur in mid-November, mid-January, and early February. Winter will be warmer and wetter than normal, with above-normal mountain snows.

Corona weather in July Temperature July, 24.1C 75.4F Temperature July max. The record fastest CME associated with the August 1972 solar storm is thought to have occurred in a similar process of earlier CMEs clearing particles in the path to Earth. Liu, professor at China's State Key Laboratory of Space Weather, estimated that the recovery time from such a disaster would have been about four to ten years. Our Sun is surrounded by a jacket of gases called an. However, the corona can be viewed during a total solar eclipse. That makes it difficult to see without using special instruments. The corona is usually hidden by the bright light of the Suns surface. ![]() A 2013 study estimated that the economic cost to the United States would have been between US$600 billion and $2.6 trillion. The Short Answer: The Sun’s corona is the outermost part of the Sun’s atmosphere. The resulting geomagnetic storm may have had a strength of −1,150 to −600 nT, comparable to the impact of the Carrington Event. ![]() Had the CME hit the Earth, it is likely that it would have inflicted serious damage to electronic systems on a global scale. The event occurred at a time of high sunspot activity during solar cycle 24. Interaction between the primary CME and the preceding CMEs as they traversed the interplanetary medium also led to amplification of the magnetic field of the ejecta that continued by the time the primary CME reached Earth's orbit. īased on the collected data, the eruption consisted of two separate ejections which were able to reach exceptionally high strength as the interplanetary medium around the Sun had been cleared by a smaller CME four days earlier. The CME travelled from the Sun to Earth's orbit in about 20.78 hours, indicating an average speed of 2,000 km/s (1,200 mi/s). The leading shock wave associated with the CME was travelling radially at a speed of around 3,300 km/s (2,100 mi/s) relative to STEREO-A by the time it reached the spacecraft. Spacecraft observations recorded the shockwave at 20:55 UTC on 23 July while the magnetic clouds arrived two hours later. The spacecraft is a solar observatory equipped to measure such activity, and because it was far away from the Earth and thus not exposed to the strong electrical currents that can be induced when a CME hits the Earth's magnetosphere, it survived the encounter and provided researchers with valuable data. The eruption tore through Earth's orbit, hitting the STEREO-A spacecraft. The CME expelled a pair of adjacent magnetic clouds that drove a fast-moving shock wave outward from the Sun. The eruption emanated from solar active region 11520 and coincided with what was at most an X2.5-class solar flare. Which is the sunniest month in Corona July is the sunniest month with an average of 369 hours of sunshine. Which is the driest month in Corona June is the driest month with 1mm (0.1in) of precipitation. The event occurred in 2012, near the local maximum of sunspots that can be seen in this graph.Īt 02:08 UT on 23 July 2012, a large coronal mass ejection (CME) was launched from the Sun. Which is the wettest month in Corona February tops the wettest month list with 93mm (3.7in) of rainfall. ![]()
