Chromospheric Vector B for 2003 Oct 29 (A Work in Progress) T. Metcalf, K.D. Leka, D. Mickey MURI Meeting, 2004 Mar 1

Data Summary ● The pre-flare NaD magnetogram has excellent data quality. ● The magnetograms during the flare have poor seeing. ● The NaD profiles in the flare are partially in emission making analysis very difficult. Pre-flare18:46Very Good Pre-flare20:26+20:31+20:36Poor Seeing Flare20:41Poor Seeing, NaD in emission 20:47Poor Seeing, NaD in emission 20:52Poor Seeing, NaD in emission 20:57+21:03Poor Seeing, NaD in emission

Pre-flare Magnetogram ● Pre- flare gram

Pre-Flare Energetics ● We can determine the magnetic energy using the magnetic virial theorem ● For the pre-flare gram: Total Magnetic Energy(7.3 +/- 1.0) x 10^33 ergs Potential Energy3.7 x 10^33 ergs Free Energy(3.6 +/- 1.0) x 10^33 ergs Open Field Energy73. x 10^33 ergs

Just Before the Flare

20: :03: NaD NOT in emission

20: :03: NaD in emission

Can you tell where the flare is?

“Post”-Flare Energetics ● For the “post”-flare gram: Total Magnetic Energy(14. +/- 6.9) x 10^33 ergs Potential Energy2.5 x 10^33 ergs Free Energy(11. +/- 6.9) x 10^33 ergs Open Field Energy94. x 10^33 ergs
