Just this week, on Monday, January 28, space weather forecasters have warned a coronal hole had opened in the Sun and is facing the Earth. A coronal hole is facing our planet today and we wanted to talk a bit about the transitional period that we are in now between Solar Cycle 24 and Solar Cycle 25. Hourly. Thus, solar particles escape at a rate great en… Breaking news today from the Solar Cycle 25 Prediction Panel! ... TODAY'S PAPER. Coronal holes on the sun’s surface are the source of open magnetic field lines and are areas from which high-speed solar wind particles stream out into space. SolarHam.com launched on March 15, 2006 with the purpose of providing real time Space Weather news and data from various sources, all in one location for easy navigation. Returning Coronal Hole A substantial coronal hole rotated across the face of the sun this past week and is again streaming solar wind towards Earth (Jan. 30 - Feb. 2, 2017). Give your support for our organization by making a donation. The Sun contains magnetic fieldsthat arch away from areas in the corona that are very thin due to the lower levels of energy and gas, which cause coronal holes to appear when they do not fall back. A hole, known as a coronal hole, has opened up in the atmosphere of the Sun’s southern hemisphere. The first meaningful mention of a sunspot was in around 300 BCE, by the ancient Greek scholar Theophrastus, student of Plato and Aristotle and successor to the latter. Coronal holes are places where the sun's magnetic field opens up and allows the solar wind to escape. Several coronal holes (CH) are currently spread across the visible solar disk. Coronal holes are the source of fast solar wind streams which sometimes have the potential to produce minor to moderate geomagnetic storms. 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. Video. Long duration solar flares are known to produce coronal mass ejections so the question is... was this an eruptive event? Coronal holes make for a gusty solar wind. However, our Sun has been relatively quiet during the first few months of the new solar cycle. Two new sunspot regions have rotated into view on the south-east limb. This is good news for Northern Lights enthusiasts, who have more chances to catch a better glimpse of … 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. Our organization promotes these scientific branches onto the world wide web with websites as this one. X-ray images of the Sun made during the 1970s by the U.S. Skylab astronauts revealed that the corona of the Sun is not homogeneous but often exhibits “holes”—regions within the solar atmosphere in which the density of gas is lower… Solar Cycle 25 is underway. A long duration C7.41 solar flare peaked today at 16:32 UTC. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online! Sunspot region 2787 was to blame. 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. This website relays data and imagery from the following sources. Propagation Long distance low and medium frequency (below 2 MHz) propagation along paths north of due west over upper middle and high latitudes is poor to fair. Radar. A C1.2 solar flare took place today at 07:21 UTC and came from a sunspot region on the Sun's northern hemisphere. These features were discovered when X-ray telescopes were first flown above the earth's atmosphere to reveal the structure of the corona across the solar disc. Sunspot region 2790 is to blame and that is a sunspot region facing 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. Nothing out of the ordinary as our Sun slowly starts to ramp up towards solar maximum which should take place in 2025. Sunspot region 2790 which decayed over the past few days and seemingly only has a simple magnetic layout, delivered with a long duration C7.4 solar flare. Coronal Holes: 05 Dec 20. This is the second M-class solar flare of the current solar cycle and the strongest solar flare of this cycle thus far. Credit: SDO/AIA. Coronal Hole Seen Over Sun's North Pole A space telescope aimed at the sun has spotted a gigantic hole in the solar atmosphere — a dark spot that covers nearly a quarter of our closest star, spewing solar material and gas into space. Coronal Hole in the Sun. C1 solar flare and CME, glancing blow possible, Prediction for Solar Cycle 25 by Dr Keith Strong. On this page you will find all the information you need to spot any coronal holes on the earth-facing solar disk. Coronal holes are the source of strong solar wind gusts that carry solar particles out to our magnetosphere and beyond. Solar wind flowing from this narrow coronal hole could reach Earth on Dec. 8th or 9th. Site Information. Coronal holes are places where magnetic field lines don’t close back on themselves, but instead stick straight out into space. It is now official, the solar minimum between Solar Cycle 24 and 25 took place December 2019 when the 13-month smoothed sunspot number fell to 1.8. Although the Sun's corona has been observed during total eclipses of the Sun for thousands of years, the existence of coronal mass ejections was unrealized until the space age. The site was created and is still maintained solely by amateur (HAM) radio station Kevin VE3EN. Give your support for our organization by making a donation. A coronal hole solar wind stream is expected to arrive at our planet today (24 December) and this could result in active geomagnetic conditions (Kp4) later today. An extensive coronal hole rotated towards Earth over several days this week (May 28-31, 2013).

Today. The massive coronal area is one of the largest we have seen in a year or more. Sunspot region 2782 which is located near the south-east limb produced a long duration C2.6 solar flare which peaked today at 19:11 UTC. The earliest surviving record of deliberate sunspot observation dates from 364 BCE, based on comments by Chinese astronomer Gan De in a star catalogue. Big news about SpaceWeatherLive today! Our organization promotes these scientific branches onto the world wide web with websites as this one. How to confirm on any coming geomagnetic storm ? On this page you will find all the information you need to spot any coronal holes on the earth-facing solar disk. Coronal holes were first seen in images taken by astronauts on board NASA's Skylab space station in 1973 and 1974. Some sunspot cycles have one coronal hole in one rotation period and some have two coronal holes in one solar rotation period. We even see an opening near the equator that has already passed the central meridian. Associated with the solar flare were a coronal wave and coronal dimming. Coronal holes are the source of fast solar wind streams which sometimes have the potential to produce minor to moderate geomagnetic storms. This leaves an open channel, out of which the solar wind can blast unobstructed. July 14, 2016. A coronal hole is facing our planet today. They appear dark because they are cooler, less dense regions than the surrounding plasma and are regions of open, unipolar magnetic fields. 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. 10 Day. Tuesday, 24th November 2020. Sunspot region 2790 is to blame and that is a sunspot region facing Earth! Solar wind flowing from this region should reach Earth on June 5-7, 2012, possibly stirring geomagnetic storms. Coronal Hole Credit: SOHO - EIT Consortium, ESA, NASA. Coronal Holes Coronal holes appear as dark areas in the solar corona in extreme ultraviolet (EUV) and soft x-ray solar images. As the coronal hole has rotated around the sun’s surface and now faces our planet, the winds are stronger and there is a spike in geomagnetic activity. Long duration solar flares are known to produce coronal mass ejections so the question is... was this an eruptive event? Do I need to be concerned about the latest C class solar flare that is heading towards earth. Parsec vzw is a non-profit organization from Belgium which consists of several websites about Astronomy, Space, Space Weather, aurora and related subjects.
