Credit: SDO/AIA. As mentioned in the news article yesterday, this solar flare was eruptive and it quickly became apparent that it launched a coronal mass ejection which is likely to hit Earth. Big news about SpaceWeatherLive today! A long duration C7.41 solar flare peaked today at 16:32 UTC. They can be seen for a long … Radar. Fig. Sunspot region 2790 is to blame and that is a sunspot region facing Earth! Explanation: This ominous, dark shape sprawling across the face of the active Sun is a coronal hole-- a low density region extending above the surface where the solar magnetic field opens freely into interplanetary space. A hole, known as a coronal hole, has opened up in the atmosphere of the Sun’s southern hemisphere. May 27, 2016. Our organization promotes these scientific branches onto the world wide web with websites as this one. How to confirm on any coming geomagnetic storm ? What a surprise event we got yesterday! Long duration solar flares are known to produce coronal mass ejections so the question is... was this an eruptive event?

No obvious coronal holes are currently in or near Earth facing positions. Coronal mass ejections (or CMEs) are huge bubbles of gas threaded with magnetic field lines that are ejected from the Sun over the course of several hours. Solar wind flowing from this narrow coronal hole could reach Earth on Dec. 8th or 9th. Sun's Coronal Hole. Solar activity reached moderate levels today as an M4.44 solar flare (R1-minor) peaked at 13:11 UTC. Other articles where Coronal hole is discussed: geomagnetic field: Cause of magnetic storms: …storms is the existence of coronal holes around the Sun. The massive coronal area is one of the largest we have seen in a year or more. These sunspot regions have received sunspot number 2785 and 2786. SpaceWeatherLive.com is a near live website where you can follow space weather from the Sun to Earth and know exactly when you can see aurora. How to confirm on any coming geomagnetic storm ? Analysis indicates that the isolated, negative polarity CH identified as CH45- will likely connect with Earth later on Wednesday, 31 July, 2019 and result in unsettled to active levels of geomagnetic response. The NOAA SWPC has issued a minor geomagnetic storm (G1) watch for this Thursday (22 October) as a high speed solar wind stream from the northern polar coronal hole is expected to arrive at Earth. The dark area across the top of the sun in this image is a coronal hole, a region on the sun where the magnetic field is open to interplanetary space. Breaking news today from the Solar Cycle 25 Prediction Panel! Coronal holes are areas in the Sun's atmosphere that appear dark in X-ray and ultraviolet images of the Sun. On this page you will find all the information you need to spot any coronal holes on the earth-facing solar disk. Some sunspot cycles have one coronal hole in one rotation period and some have two coronal holes in one solar rotation period. Our organization promotes these scientific branches onto the world wide web with websites as this one. Coronal Holes Coronal holes appear as dark areas in the solar corona in extreme ultraviolet (EUV) and soft x-ray solar images. Coronal holes are places where the sun's magnetic field opens up and allows the solar wind to escape. Coronal mass ejections (CMEs) December 3-5: No obviously Earth directed CMEs were observed in available LASCO imagery.. Coronal holes [Coronal hole history (since October 2002)][Compare today's report to the situation one solar rotation ago: 28 days ago 27 days ago 26 days ago] A small recurrent trans equatorial coronal (CH981) rotated across the central meridian on … Coronal holes are the source of strong solar wind gusts that carry solar particles out to our magnetosphere and beyond. Sunspot region 2787 was to blame. An extensive coronal hole rotated towards Earth over several days this week (May 28-31, 2013).
