Hi Folks, Last week a good set of prominences, today (and yesterday--sorry didn't get it posted) there's a couple of complex sunspot groups that are the main attractions. In Ha light, you can see that they're interacting with each other (yesterday, it looked like almost classic bar-magnet lines between the two groups: arched lines in the chromosphere plasma between the two groups). I also saw one of the groups throw off a couple of flares yesterday. I haven't tried looking in white light, but I imagine they'd be interesting that way also. John
