I realized some time ago that my hobby - solar imaging - is actually a lot like fishing. You hang out on the forums, buy all the mysterious gear, then on a sunny day (with good "astronomical seeing") you set up in the field and record raw material for up to a few hours (for later processing), hoping for something to happen (a surge, flare, spectacular prominence). Needless to say, the Sun sometimes doesn't cooperate and you go back empty-handed. But when some "big" transient occurs (timescales here can be <1 hour) - so satisfying!
