June 5 update: CME taking a punch today?

Today’s most important sun news: A CME glimpse of the 1 June filament eruption is expected today, June 5, 2022. (See the tweet below.) The arrival time is 18 GMT 2 p.m. EDT), plus or minus about 7 hours. In other words, the CME may reach us sooner or later. And it can totally miss us. But it could hit us, giving us active geomagnetic conditions for the remainder of June 5 and through June 6. a geomagnetic storm is not predicted, but CMEs can always surprise us. What does it mean for aurora viewers? We may have increased aurora activity at higher latitudes, with the possibility of aurora showing up at slightly lower latitudes. Clear skies and fingers crossed!
Last 24 hours: Very low sun activity continues. There are only class B flares (“too small to harm the earth” on the) Stanford scale† None of the six sunspot regions are very active. AR3028 and AR2039 are newly formed regions and three others are about to disappear from view.
Next 24 hours: Today’s forecast is a 50% chance of C torches5% for M flares and 1% for X flares.
Next expected CME: Other than today’s possible glare, there are no others aimed at Earth CMEs.
Current Geomagnetic Activity: Quiet.

June 4 update: The sun is still

The sun is still still. There are only class B flares (“too small to harm the earth” on the) Stanford scale† We have seen five solar flares, the largest B8.14 from sunspot region AR3024. Sunspot region AR3026 is nearly disappearing at the northwestern rim (edge) of the sun, performed by the sun’s rotation.

June 3 Update: Double Filaments with Double CMEs

two beautiful filament eruptions produced CMEs yesterday. One eruption was from the southeastern rim and a near-simultaneous eruption came from the southwestern disk. None of the CMEs are aimed at Earth. The southeastern eruption also caused a C1.2 eruption† Otherwise, the solar activity is very low.

June 2 solar activity update: AR3027 a confused sunspot

Sunspot region AR3027 is confused when it comes to its magnetism. the law of Hale tells us that before Solar cycle 25, the magnetic field of sunspots in the southern hemisphere of the sun should start with negative and end with positive (negative on the right and positive on the left). Sunspots in the Northern Hemisphere are the opposite of that, positive on the right and negative on the left. All current sunspots follow this law…except one. The newly formed sunspot region, AR3027, is backward. This is known to happen, but it is very uncommon. What does it mean? Swapped sunspots can often mean they have a much greater potential to explode and produce solar flares and CMEs† We wait and see if something exciting happens.

Update June 1: Parker Solar Probe is halfway through

Parker solar probe – first spacecraft to touch the sunLaunched in 2018 – today is half of its seven-year mission. Today Parker Solar Probe makes its 12th close approach to the sun (5.7 million miles or 9.2 million km). In total, the mission will make 24 close approaches. Its next close approach is September 6, 2022. Its absolute closest approach will come in December 2024, when it will sweep within 4 million miles (6.2 million km) of the solar surface at speeds exceeding 430,000 miles per hour (692,000 km/h). ). ), closer than any other spacecraft has ever come to our local star.

Update May 31: Sunspots develop on the other side of the sun

Solar activity has remained at a very low level in recent days. But we could see an increase in a few days. That’s because three sunspot regions are developing on the far side of the sun. This solar activity is seen through the use of helioseismology, a technique that uses sound waves propagating in the sun. Just as geologists study seismic waves from earthquakes, solar physicists study these sound waves to understand what we can’t see. Flaring usually continues at the B-class level. Activity is spread across the drive, coming from AR3023, AR3024, and AR3025. The biggest event, C1.5, came from above the limb (behind the rim of the visible disk), of the now-departed AR3019.

This is an image from May 31, 2022 showing the sun’s activity on the far side of our sun. The 3 yellow circles show developing sunspot areas. The images are obtained using helioseismologymade with data from the SDO HMI instrument.

May 30 update: A very quiet sun

The sun has reached an almost eerie calm after so many weeks of exciting solar activity. We patiently wait for the action to pick up. We know it will happen.
Flaring of the sun is at a very low level. Only three numbered sunspot groups are visible. AR3021 has disappeared and has been replaced by a newly emerging region near the northwest rim, AR3025. AR3023 and AR3024 remain stable and very quiet. We have seen almost exclusively B-class flares with a C1.4 eruption from AR3023 and a C1.5 eruption from the northwestern part near where AR3019 was. no CME currently expected. Geomagnetic activity is silent.

A week of sun activity: 19 to 26 May

Large, fiery setting sun with small dark spots.

Several sunspots are visible, including AR3023. There are also some nice prominences.” Thank you!

What it comes down to:: June 4, 2022: Sun activity remains low. Solar cycle 25 is similar to solar cycle 24. But this solar cycle is just beginning; activity will increase in the coming months and years.

Why are east and west on the sun reversed?
