NOTES: Just a heads-up on increased solar activity. There are some very large and prominent sunspots currently crossing the solar central meridian. One especially large group (sunspot # 1302) is an easy naked-eye group (with proper white-light filtering) which I observed today (9/28/11). In H-alpha the sun is showing some large and nice prominences with amazing detail in the magnetically-aligned filaments and swirls surrounding the larger sunspots. Even if you only have a white-light solar filter, the views are amazing! |
