Sun in H-alpha, July 10, 2025

Описание: View through my Lunt 40 Hydrogen-alpha solar telescope on July 10, 2025!

Similar to my Seestar S50 videos, this is a look through my own telescope 🔭- my Lunt 40 Hydrogen-alpha Solar Telescope.

Today, the sunspot # was 83. The H-alpha view shows a number of active regions, filaments, and 2 small areas of prominences (proms).

The new active regions AR4135, 4136, & 4137 look huge and some are active!

You can compare this view to the videos from
NSO GONG (also H-alpha).

The GONG network of instruments is hosted by the Big Bear Solar Observatory, High Altitude Observatory, Learmonth Solar Observatory, Udaipur Solar Observatory, Instituto de Astrofísica de Canarias, and Cerro Tololo Interamerican Observato

Sunspot Clusters are also known as or called Active Regions.

Area of sunspots are measured in millionths of a solar hemisphere (MH).

Flare strength is rated on a scale that includes C-class, M-class, X-class and Proton-class flares.

What are Sunspots?- Sunspots arise from magnetic disturbances that change how the outer layers of the sun regionally mix, uncovering cooler spots that appear darker on the surface of the sun.

What's the point?- Sunspots and sunspot clusters are part of solar active regions (AR). We track active regions on the sun because they can cause solar flares and coronal mass ejections (CME). Particles ejected from CMEs can hit the Earth several hours later (as soon as 15 hours or up to several days later) and cause aurora, and large solar storms can do damage to electronics, our electrical grid and satellites. Plus, sunspots look cool, and they are huge! Some can be several times the size of Earth.

Why should I care?- The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. A geomagnetic storm of this magnitude occurring today has the potential to cause widespread electrical disruptions, blackouts, damage and human health due to extended cuts of the electrical power grid. A Carrington-class event today would result in between $0.6 and $2.6 trillion in damages to the U.S. alone.

Sun Observation- I try to post daily updates relatively early in the day so that others that have interest can see what's going on. I have heard from some other solar astronomers that they appreciate these short videos to see whether or not it's worth getting out their Hydrogen-alpha (H-alpha, Ha) solar telescopes, and it also gives them a preview of the sunspots and active regions.
