WEATHER COMMENT: Sun Feb 19 17:16:20 GMT 1995
Cool, clear, light southwest wind.  Temp=42F.


MKIII COMMENT: Sun Feb 19 17:22:40 GMT 1995
Tried using only puffs from bulb to clean O1.

Sun Feb 19 17:23:27 GMT 1995: Patrol Start

MKIII COMMENT: Sun Feb 19 17:51:16 GMT 1995
Coronal image noisy at E and W wings, P+S looks a bit high.
Unsure if that is the sky or dust on O1 that is difficult to
remove with puffer.

MKIII COMMENT: Sun Feb 19 18:09:07 GMT 1995
Must've been sky, noisy wings are gone.


MKIII COMMENT: Sun Feb 19 19:01:39 GMT 1995
Pockets of something can be seen in P+S signal occasionally moving
across scan.

DPMON COMMENT: Sun Feb 19 19:22:19 GMT 1995
Faint top[ of arch or loop prominence visible at PA 240 about
1.2 RV.  Hard to discern, but may have a footpoint at or near
prominence that was visible this morning at PA 230.


DPMON COMMENT: Sun Feb 19 19:31:32 GMT 1995
I don't see that prominence top at PA 240 any more.  It either
faded or moved out of FOV very rapidly.


MKIII COMMENT: Sun Feb 19 19:36:19 GMT 1995
Enhancement in corona overlying prominence activity region.  There
is also some streaking-type artifacts in VDIFF.  Checking it out.


MKIII COMMENT: Sun Feb 19 19:43:14 GMT 1995
There was a smudge on the back surface of the  O1.  Wiped it off
with a cleaning tissue and dusted off O1 with bulb.


MKIII COMMENT: Sun Feb 19 20:00:39 GMT 1995
CME is definitely occurring over PA 240. Subtle effects seen between
PA 240-290.  Streaking artifact seems to be gone.  Must've been
the contamination on the O1.

COMMENT: Sun Feb 19 20:12:27 GMT 1995
Sent out preliminary CMELST alert.


MKIII COMMENT: Sun Feb 19 20:22:29 GMT 1995
Coronal changes still seen in current VDIFFs, changes do not
show up on high resolution NDIFFs.


MKIII COMMENT: Sun Feb 19 20:53:01 GMT 1995
Coronal changes either gone or very subtle.
