KEYHOLE OPERATIONS:
*******************
11/15 - 12/02: 26 m keyhole
11/19 - 11/28: 34 m keyhole

* 11/19 11:00 UT - 11/24 11:00 UT: EIT CCD Bakeout 
 (EIT will resume observations on ~ 11/24 @ ~20:00 UT).

* 11/20: SOHO S/C 180 deg Roll.

	01:33 - 16:50 UT	LASCO Data Gap (C2 time).
				(NO LASCO DATA)

17:50 UT  NN East	Very thin loop (jet-like) front.

09:26 UT  S East	Thin and very diffuse loop front.

11:06 UT  SS East	Jet-like front.

11:50 UT  EN East	Very faint ragged front. Difficult to give an exact 
			time of first appearance. Couple of fronts follow by
			15:26 UT and then later by 18:06 UT. The event fades
 			throughout C3.
