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.

Solar Maximum Reached
10/16/2024

NASA LogoIn a conference today NASA, NOAA, and the International Solar Cycle Prediction Panel announced that the Sun is in its solar maximum period where sunspots, flares, and other activity are at their greatest. This period will last approximately a year according to scientists. Such activity can lead to aurora, such as those seen deep into the continental US last week. Scientists will not be able to determine the exact peak of this solar maximum period for many months because it's only identifiable after they've tracked a consistent decline in solar activity after that peak.

Another Large Eruption
5/14/2024

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.
