Hi MN0NDX,
I'm not sure how magnetically complicated 743 is, but it looks a decent size. 742 might have some potential if it keeps growing. One of those, or even 741, has kicked out a C4 flare this morning. The previous C1.8 on the plot was from 741.
It sometimes pays not to take your eye off the ball, as these guys in Northern Ireland found out when unexpected Aurora were visible on 5th March. I hadn't received any warnings either for that day.
