Coronal Diagnostic Spectrometer

Synoptic:

full sun images (14, 21, 28 Aug, 4 Sep)
daily synoptic images along the central meridian (4 arcminutes wide).

Special:

North pole and South pole images (Normal Incidence Spectrometer - NIS):
• North Coronal Hole: 16, 17, 24, 25, 31 Aug, 7 Sep

• South Coronal Hole: 11, 18 Aug, 1, 8 Sep

East limb, West limb studies, including NIS 4'x4' images and Grazing Incidence Spectrometer (GIS) spectra:
• East Limb (GIS+NIS): 13, 20, 27 Aug, 3, 6 Sep

• West Limb (GIS+NIS): 19, 22, 26, 29 Aug, 2 Sep

NIS limb images (without GIS spectra):
• East Limb: 24 Aug (active region), 30 Aug

• West Limb: 12, 15 Aug, 5 Sep

Also a campaign of coronal hole studies (with emphasis on the boundaries) was carried out during the last three weeks of August. This consisted of combinations of GI and NI studies spanning the boundaries and included studies of the equatorial coronal hole which appeared in the last week of August. (Contact: Barbara Bromage)
