Our Facebook administrator and Webmaster, and original member of the McMath-Hulbert Astronomical Society, Marty Kunz, passed away in April 2024. The remaining members have been active in many other areas but have neglected the website and pages. We sincerely apologize and are beginning to rebuild these important communication methods.
We had a lot of difficulty with the website, and have purchased a new domain at www.MHAS.us and have begun populating it with appropriate content.

In a study published in The Astrophysical Journal, researchers from the Yunnan Observatories of the Chinese Academy of Sciences depicted a complete physical image of the anomalous heating in the upper atmosphere of the sun (the solar corona and the solar chromosphere).

The Sun emitted a strong solar flare, peaking at 1:53 a.m. EST on Friday, February 16, 2024. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications,

From Spaceweather.com SOLAR ECLIPSE COMET: Anticipation is building for a rare sight during this April's total solar eclipse. In addition to the sun's corona, there's going to be a comet. 12P/Pons-Brooks will be close to the sun during totality, potentially visible to the naked eye inside the Moon's shadow.

No, you’re not seeing double. The Sun just flung out two massive flares of radiation from opposite hemispheres at nearly the same exact moment, a sign that our host star is fast approaching a period of peak activity.

Much like the Earth, our sun is a dynamic body with a complex—and sometimes violent—weather system. Solar storms eject highly energetic radiation that can impact our planet, forming strong auroras and disrupting power grids, electronics, and satellites.

Researchers at IISER Kolkata's Center of Excellence in Space Sciences India have uncovered a novel link between the Sun's magnetic field and its sunspot cycle. This finding could enable predictions of the peak in solar activity. According to their study, the peak of solar cycle 25, which is currentl
