A "well-behaved" CME-ICME event
Two consecutive halo CMEs originated from the Sun from almost the same region, one at ~ 18 UT, May 23, and the other at ~ 14 UT, May 24. The question is we should expect to find two consecutive ICMEs at 1 AU, as well as in SECCHI HI observations. Is this kind of double CMEs showing up?
