	An X1.6 flare and wave near Sun Center and a nearly symmetric halo CME on Sept. 10. The ICME at L1 on 12-13 Sept., following two IP shocks, mostly had strong northward field in the putative flux rope (several models produced). The southward fields, which drove the early storm activity, were in the sheaths trailing two IP shocks, the second one being the strongest. The ICME north field rapidly shut down the auroral and storm activity.		An X1.6 flare and wave near Sun Center and a nearly symmetric halo CME on Sept. 10.

For this event people predicted either WSE or SEN with Bz<0, and LH. [Plot from Nariki Nitta on Sept. 15, 2014]		*Nitta's plot of ACE RTSW data in the style of K.

		+	*THE "FORBUSH REBOUND": Radiation levels in the stratosphere are back to normal following a mid-September dip caused by one of the strongest solar storms in years. The story begins three weeks ago. On Sept. 12th a CME hit Earth head-on, sparking a G3-class geomagnetic storm. Using a helium balloon, the students of Earth to Sky Calculus launched a radiation sensor into the storm, expecting to measure an increase in energetic particles. Instead of more, however, they measured less. The CME had swept away many of the cosmic rays around Earth and so radiation levels in the stratosphere dropped.
		+
		+	The CME was long gone on Sept. 28th when they repeated the experiment and found radiation levels returning to pre-storm values.
		+	The drop in radiation is called a "Forbush Decrease" after the 20th century physicist Scott Forbush who first described it. This would make the bounce-back a "Forbush Rebound." According to the data, the rebound took less than two weeks and possibly only a few days. The next time a CME hits, the students plan to launch balloons with a faster cadence to better measure the stratosphere's response time.
