Solar
The Association of Lunar and Planetary – Solar Section was formed in 1982 at the request of the founder and then Director, Walter Haas. We defined our observational goals then as being the coordination of optical observations of solar morphology. We do not count sunspots but use such statistics from several international sources all of whom do a far better job of it than we could. Our first 40 years have been highly successful with contributions from a number of countries filling our files today. Whatever telescope you have, with proper safe filtration, can make useful contributions to the work of the Section. So join the Solar Section get observing and as you observe you will learn about other instruments, techniques and filters from other more experienced observers.

Another Large Eruption

Top 10 Website khoa h?c n?i ti?ng nh?t th? gi?i - Toplist.vnThe strongest solar flare in over 5 years exploded off the Sun from the same sunspot group that recently caused a wide-ranging aurora display. However, this one is unlikely to result in any aurora since the sunspot is located at the very edge of the visible side of the Sun. Even so, high-frequency radio blackouts are still likely on Earth. More details here.

Surpise Aurora!
3/24/2023

SpaceWeather.comForecasters did not see this one coming! On March 23-24, auroras spread into the United States as far south as New Mexic0 during a severe (category G4) geomagnetic storm--the most intense in nearly 6 years. The cause of the storm is still unclear; it may have been the ripple effect of a near-miss CME on March 23rd.
