A little solar activity this week

In summary, despite overall disappointment with Solar Max, there have been brief bursts of good activity and a large sunspot group AR2403 has been traversing the solar face. However, it has not been very active in producing flares, with only 6 x M class flares so far. A photo was taken on August 25th, 2015 using a 800mm lens and solar filter, and the person has been regularly checking solar satellites for updates and has a database of images spanning back to the 1990s.

Overall this Solar Max has been pretty disappointing. But occasionally the Sun as shown brief bursts of good activity
over the last week, and for a few more days, there has been a large sunspot group traversing the solar face.
AR2403 is a massive spot group and one of the largest this solar max. But it hasn't been overly active in the flare production department. So far 6 x M class flares, the largest being a M 5.6

Here's a pic I took yesterday 25 Aug 2015
800mm ( 400mm and 2x teleconverter), f11, ISO 250, 1/250th sec exp and a full aperture solar filter
was a bit of an act to get the shot as the sun came and went behind the thick rain clouds

Nice photo.

Have you checked on any of the solar satellites to see if they've seen something?

http://sohowww.nascom.nasa.gov/data/realtime-images.html
hi you :smile:

I used to use that site, but their image quality sucks these days
I use this one instead ...
http://umbra.gsfc.nasa.gov/images/latest.html

so much better quality !

I download the Fe 171, He 304, magnetic, intensity and x-ray images daily ( each morning before going to work)

Have a database of images spanning back to the mid 1990's when SOHO first came online
and now more recently superseded by SDO ( Solar Dynamics Observatory) space craftDave

FAQ: A little solar activity this week

What is solar activity?

Solar activity refers to the changes and fluctuations that occur on the surface of the Sun, such as sunspots, solar flares, and solar prominences.

How is solar activity measured?

Solar activity is measured using various instruments, such as telescopes, satellites, and ground-based observatories. These instruments measure different aspects of solar activity, such as the number and size of sunspots, the intensity of solar flares, and the strength of the solar wind.

Why is solar activity important?

Solar activity has a significant impact on Earth and its environment. It can affect weather patterns, satellite communications, and even the Earth's magnetic field. Understanding solar activity can also help scientists predict and prepare for potential hazards, such as solar storms.

What causes solar activity?

Solar activity is primarily caused by the Sun's magnetic field, which is constantly changing and interacting with the Sun's hot plasma. This can lead to the formation of sunspots, solar flares, and other phenomena.

Can solar activity affect our health?

Solar activity can indirectly affect our health by impacting Earth's climate and weather patterns. It can also have an impact on satellite communications, which can affect our daily lives. However, solar activity does not have a direct impact on human health.
