Observe The Sun Safely – Never look at the Sun without a proper filter!
Solar Programs are held 1st Sunday of every Month 2:00-4:00 PM at Houge Park weather permitting.
I expected a less than average turnout this Labor Day weekend. Yet we had 4 Solar Scope Setups and a nice crowd of folks (thanks to all for coming out) that kept the event going past 4:00 o’clock.
And speaking of that O’clock we noted superb H-Alpha flares (quiescent prominences) at 7, 9 and 12, refactor view, and one “Bic lighter” H-Alpha active flare (surge prominence) at 8 o’clock on the solar dial. The quiescent flares extended some 40,000 miles from the Sun and extended along the Sun 70-80 thousand miles. The narrow surge prominence extended some 80,0000 miles form the surface before we saw it’s upper region dissipate.
At it’s peak the solar dynamo is sizzling and dazzling. In Keven Lahey’s 10 inch scope we counted 28 sunspots in 4 groups giving a sunspot count of 68. Actually I incorrectly counted four groups instead of three. Had I not done that my estimate would have agreed with the ISN, International Sunpot Number of 58. Below is an image of the Sun for September 1st.
Three Sunspot Groups and a total Number of 28 sunspots gives Sunspot Number (SN = G+N) of 58.
Look forward to seeing everyone next Solar Meetup at Houge October 6th!
