SHINE Campaign Event: 1-2 May 1998
Brian Welsch (& Yan Li)Space Sciences Laboratory, UC Berkeley
• Introduction: Data, Context, etc.
• Work: Completed & Ongoing
• Poster Previews!
• The Punchline
Primarily Interested in Two Halo CMEs:
22:30 UT 1 May & 13:30 UT 2 May
1) Solar Source Region: AR 8210
2) MDI Full-Disk, Carrington Rotation 1935
Photospheric Field Evolution• Sub-Region of MDI Full-Disk Movies
• AR flows are hot topic: three new methods to find 3-D flows, e.g., ILCT – More about flows in Poster previews!
– Modelers using these data to simulate eruptions!
Development in Low Corona
• Yohkoh SXT: Connections with AR 8214! – CMEs global? Model-in-box problematic?– Nearby coronal hole?
• CME-associated GOES Flares: 1. M-class @ 22:30 UT 1 May,
2. X-Class @ 13:32 UT 2 May
Development of CME #1
• Pre: H- /EIT crinkles away from “core” indicative of breakout-type reconnection? (Sterling & Moore, 2001)
• EIT 195 Movie, S. Regnier
• Halo CME, LASCO C2
Development of CME #2
• H Images (Kanzelhöhe Sol. Obs.)
• Blast Waves: Pohjolainen et al., 2002 ;
Wills-Davey ; Warmuth et al., 2001
• Radio Sources: Pohjolainen et al., 2002 * *
• Post: Dimmings in SXT *
• Halo CME *
Helio- & Magnetospheric in situ Data
• Multiple-CMEs Disturbed IP environment!– Effects of CME #1 difficult to discern
• ACE/WIND Data: Shock, Southward Bz *
• CME #2 was significantly geoeffective *
Basis for Selection as SHINE Event
• CME #1 also chosen as a MURI Event, for driving coronal MHD codes from magnetograms (see Bill Abbett’s talk, tomorrow a.m., WG I.): – time series of Imaging Vector Magnetograph (IVM)
data prior to flare & eruption
• Good data coverage! But interpretation of CME #1’s effects in situ CME #1 aren’t clear.
Basis for Selection as SHINE Event
• CME #2 is well-observed on disk in multiple data sets, and was strongly geoeffective.
Poster Previews
• Loraine Lundquist et al.* (#48)
• Manolis Georgoulis & B. La Bonte * (#51)
• Dana Longcope * (#7)
• Ilia Roussev et al. * (talk tomorrow, WG #2)
Take Home Points, a.k.a. The Punchline
• Used Data to Display Event Context
• Introduced Completed and Ongoing WorkIncluding some presented at this meeting!
• GOAL: Generate ‘Consensus Report!’– Special issue of JGR? – ‘Living’ article?
• Much work to be done!
And so, my fellow physicists:
“Ask not what SHINE can do for you,
but what you can do for SHINE!
We need your data!
We need your effort!
Special Thanks to Yan Li!

ILCT flows, c. 19:40 UT, 1 May
For more details, see George Fisher’s poster #96
• Inductive LCT, combined with vector magnetic field data, enables us to find 3-D flow field: transverse flows are shown as arrows, up/down flows shown as blue/red contours.
