#X-FLARE CHAMPION OF SOLAR CYCLE 25: Active sunspot AR3663 produced two more X-flares today, a pair of X1's on May 8th at 0145 UT and 0509 UT. This makes it the most active sunspot of #Solar #Cycle 25 so far.

Since May 3rd, AR3663 has tallied six X-flares, more than any other #sunspot in the past 7 years. It may continue to run up the score as it approaches the sun's western limb later this week.

EARTH-DIRECTED #CME: A CME is coming. It was hurled into space earlier today by a roiling series of explosions in the magnetic canopy of giant sunspot AR3664. This movie from the Solar and Heliospheric Observatory shows the CME leaving the sun bracketed by Venus (right) and Jupiter (left):

A NOAA forecast model predicts the CME will reach Earth late on May 10th, sparking G1- to G2-class geomagnetic storms on May 11th.

A second CME might be following close behind this one. You can see a hint of it emerging near the end of the movie,

A #CME expected to hit #Earth on May 5th appears to have arrived right on time. Solar wind data suggest a close encounter around 1800 UT in good accord with NASA and NOAA predictions. The resulting G1-class geomagnetic storm sparked mid-latitude auroras in Europe:

" #Auroras surprisingly appeared here in the Czech Republic at latitude +50 N," reports photographer Petr Horálek at the Institute of Physics in Opava. "They were visible to the naked eye despite the cirrus clouds."

This might not have been a direct hit. Normally, on-target CMEs produce a sharp discontinuity in the speed of solar wind blowing around our planet. Not this time. Instead, a gentle ripple of south-pointing magnetism washed over the Earth for several hours--typical of near-miss CMEs that catch us in their wake.

More CMEs may be on the way. Yesterday's flurry of X- and M-class solar flares from hyperactive sunspot AR3663 probably hurled some debris toward Earth. Confirmation awaits overdue coronagraph data from SOHO

MOST ACTIVE #SUNSPOT IN YEARS: Fast-growing sunspot AR3663 has quickly become the most active sunspot of Solar Cycle 25. Today alone it has unleashed two #X-flares and six #M-class #flares. This interest-compressed movie from the #Solar Dynamics Observatory shows 12 hours of crackling action:

Each of these flares has created a brief but deep radio blackout on Earth, causing loss of signal at frequencies below 30 MHz. These are events easily noticed by ham radio operators, aviators and mariners using shortwave to communicate.

The flares are expected to continue. AR3663 has a 'beta-gamma-delta' magnetic field where mixed polarities are bumping together in explosive proximity. NOAA forecasters estimate a 75% chance of additional M-class flares and a 25% chance of more X-flares on May 5th.

If you build it, will they come? Insect community responses to habitat establishment at solar energy facilities in Minnesota, USA - IOPscience https://iopscience.iop.org/article/10.1088/1748-9326/ad0f72

We found increases over time for all habitat and biodiversity metrics: floral rank, flowering plant species richness, insect group diversity, native bee abundance, and total insect abundance, with the most noticeable temporal increases in native bee abundance. We also found positive effects of proximity to solar-pollinator habitat on bee visitation to nearby soybean (Glycine max) fields.

I love solar eclipse art by children and young people.
This is by a 1911 High School student.
- The Cosmic Lesson of the Solar Eclipse is that even when you can't see something, there are still incredible things happening.

Acharya Shree Yogeesh sheds light on the spiritual benefits and dangers of the 2024 Total Eclipse happening on April 8th. A Total Sun Eclipse can help activate the brain and boost ones energy when you do spiritual practices, such as mantras and meditations during this time. Acharya Shree gives specific mantras based on each Zodiac sign to help seekers create protection, special energy, and a special meditation experience. Even if you are not in the path of a total eclipse, there are still some benefits during a partial eclipse.

Russia targeted solar power plant in Ukraine's rear for the first time

Yesterday (on April 3), the enemy targeted a solar power plant. This is the first case, at least in my memory, of a targeted attack on a renewable energy facility," Kudrytskyi said, without disclosing the location of the solar power plant.

Kudrytskyi said that there is no acute shortage in the power system, as total electricity consumption is falling due to the warm weather. There is a seasonal increase in production at solar power plants, according to Kudrytskyi.

ARCTIC #AURORAS: Around the Arctic Circle, many #aurora tour guides have already packed their cameras for the end of the season. Marianne Bergli of Tromsø, Norway, is glad she waited one more night. "Auroras filled the sky on April 4th," she reports. "It was a fantastic end to our touring season."

A #solar #wind stream brushed Earth's magnetic field on April 4th. It did not cause a global geomagnetic storm; the planetary K-index peaked at 4. Nevertheless, the Arctic light show was sublime.

Soon, summer sunlight will make these displays impossible to see inside the Arctic Circle. That's why Bergli and others are going on vacation. "We start again in September," she says
