Points Of Interest
LASCO will be supporting the Equatorial Coronal Holes Campaign
(Jan 10 - Jan 13, and Jan 17 - Jan 22). The observing sequence
consists of high cadence (5 minutes) C2 orange Filter images at
100 sec exposure for 6 hours periods (14:55 - 20:55 UT) between a
pair of Pb sets. FOV: half-field (512x1024) over the West. No C3
images during that time.

around the very end of the previous day. It develops
as an elongated loop front (apparently twisted
trailing material).
