Astronomy Day at SJ MLK Public Library

Nice day for sunspots, solar flares, and Astronomy Day at the San Jose Martin Luther King Public Library. The volunteers Isaac, Teruo, Keith, Michael and Kevin made this event a success so thanks to all! But a huge thanks to the Library and staffers Deborah and Judith who helped make this stellar educational day happen! Thanks! Stargazers often say if we get one person hooked on astronomy then that makes any observing session worth it. SJAA did more than that with the 70 folks who stopped by. There were lots of “oohs” “aahs” and “wows” today and one person said he is going home and becoming a member of the San Jose Astronomy club now! Check out the Pics:

AR1726 is the fastest-growing Sunspot and, so far, the most active. It is crackling with C-class flares

Cupertino’s Earth Day

Cloudy Day At Earth Day Still Saw The Sun

From 11 to 3:30 we had about four 10-20 minute viewing sessions where we offered the public good views of a very active Sun. With Isaac and Hiedi’s H-alpha/Standard solar setups, Bill’s scope and SJAA’s we got a lot of people their first look ever at a massive sun spot plus several smaller ones and above average prominences (prototypical looper) around the solar disk. We had lines of people during these sunshine times. I probably got ~40 people views in 10 minutes ~ 15 seconds per person. During the time of clouds we talked to numerous interested folks or with interested kids the perfect age 9+/- and handed out all of our brochures. We also handed out a decent number of pamphlets on preserving our starry night sky from the International Dark-Sky Association.

Sun  2 – 4PM : SJAA’s H+Alpha Day @ Houge Park

POLAR FILAMENT ERUPTION: Not every eruption requires a sunspot. On April 1st (no fooling) a magnetic filament snaking some 800,000 km around the sun’s north pole rose up and erupted, hurling part of itself into space. NASA’s Solar Dynamics Observatory (SDO) recorded the event; 7 O’Clock on the solar dial:
