High Solar Activity


The two large Sunspot areas to the right, designated AR3712 and AR3713, have grown significantly in size to 3900 million square kilometers and 3300 million square kilometers. The dark lower Sunspot area AR3719, has become very active releasing an impulsive flare causing a radio blackout over the Pacific Ocean. 06-21-2024 Palm Springs California

AR3712 More Active

The large Sunspot area, designated AR3712, continues to grow and now exhibits a mixed polarity magentic field. This could result in flares and solar winds causing radio disruption and auroral activity on Earth. 06-17-2024 Palm Springs California


Sunspot AR3712

The large Sunspt area is designated AR3712. Covering an area five times the surface of the Earth, it had greatly increased in size in the last 24 hours. Flares and magnetic complexity could bring Auroral activity and radio blackouts. 06-15-2024 Palm Springs California


Sunspots 2,010 Million Square Kilometers

The large Sunspot area is desiganted as AR3576. It is actually 44 individual Sunspots measuring 2,010 million square kilometers. By comparison the Earth is 510 million square kilometers. 02-08-2024 Palm Springs California

Sunspots 01-16-2024

Numerous Sunspots today. The larger areas are approximately 900 million square kilometers in size. By comparison the Earth measures 516 million square kilometers. Palm Springs California

Sunspots 12-23-2023

Numerous visible Sunspot areas including AR3531 on the left and AR3529 on the right. AR3529 is 1,260 million square kilometers. That is over twice the size of the Earth. Palm Springs California

Lots Of Sunspots

Numerous large Sunspot regions after the last week with almost none. It is expected to create numerous flares, Coronal Mass Ejections, and high speed Solar Wind according to EarthSky.com. 11-23-2023 Palm Springs California

Sunspots 11-21-2023

After a number of days with minimal Sunspot activity, three Sunspots broke into greater numbers and rotated into view. This could result into more Auroral activity and geomagnetic storms. 11-21-2023 Palm Springs California.

Sunspots 11-05-2023

The large Sunspot is designated as AR3477. It is approximately 1,050 million square kilometers which is more than twice the size of the Earth.Photographed 11-05-2023 Palm Springs California.

Sunspots 10-31-2023

The large Sunspot area is designated as AR3474. It is actually made up of 30 individual Sunspots covering an area of 1,380 million square kilometers. By comparison the Earth covers an area of 510 million square kilometers. 10-31-2023 Palm Springs California

Moving Closer

Annular Solar Eclipse. The Moon moving to cover two large Sunspot areas designated as AR3464 and AR3465. 10-14-2023 Palm Springs California

Solar Eclipse 10-14-2023

Video this morning 10-14-2023, the Annular Solar Eclipse. The large Sunspot area is designated AR3465. It is approximately 608 million square kilometers in size. By comparison the Earth is approximately 517 million square kilometers. Other places geographically had more coverage of the Sun by the Moon. But here in Palm Springs I found just as fascinating.


Sunspots 09-20-2023

Numerous Sunspots 09-20-2023. The larger area is designated AR3435. At 324 million square miles, it is twice the size of the surface of the Earth.


Sunspots 09-08-2023

The large cluster of Sunspots is identified as AR3423. It has been showing significant growth and has had increasing flare activity. (EarthSky.org) The morning of 09-08-2023 Palm Springs California.


Solar Activity 08-05-2023

Recent solar activity showed CME Coronal Mass Ejections and flares causing geomagnetic storms and Auroras on Earth seen as far South as Arizona. (per EarthSky) Photographed 08-05-2023 Palm Springs California


Sunlight Through A Cloud

The Sun photographed through a thin veil of clouds. A few Sunspots visible. This morning 07-17-2023 Palm Springs California.


Sunspots 07-16-2023

Numerous sunspots with two large areas. AR3363 soon to rotate out of view, and AR3372 which has become more magnetically complex. The more complex the sunspot, the greater the potential for large flares. 07-16-2023 Palm Springs California.


Increased Sunspot Activity

Increased sunspot activity as compared to earlier this week. Photographed this morning 06-17-2023 in Palm Springs California.
