There was a large prominence that was underlying the region that is now gone. Alice first caught the event from Boulder. What a team! **** EVENT COMMENT ****: Tue Jun 16 18:56:38 GMT 1998 I am also noticing that the streamer at PA 305-330 seems to be moving poleward--or the coronal hole south of the streamer is expanding. This is based on xanim image queue 1827-1853 UT. Tue Jun 16 19:01:21 GMT 1998 PICS Flat **** EVENT COMMENT ****: Tue Jun 16 19:01:39 GMT 1998 The coronal hole must be expanding as the small streamer on the other side of it at PA 285-300 appears to be moving toward the south.

Due to the 'wrote 0 records' errors we have been getting, specifically when they interrupt activity observations, we decided to remove tape acquisition. Data acquisition to disk and later network transfer has been working very reliably. I believe scanlog will still be kept and printed out with the log each day so the observer will have some feedback as to what data were written each day. Alice is working on a disk-to-tape data transfer script so we will have a means to save data and conserve disk space should there be an extended network outage of more than 4 or 5 days.
