SOHO and the 2006 Eclipse

Support observations

To the SOHO Eclipse 2006 page

Since the MDI instrument is in a 60-day continuous contact period, none of the instruments will be in record. The spacecraft will be in submode 5 around the time of the eclipse. Eclipse observations form also SOHO campaign number 7175. Following SOHO instruments are planning to support the ground-based eclipse observations:

CDS

CDS will perform a semi-circular scan along the south limb of the Sun, observing the off-limb corona. The timing of the scan will be such that CDS will observe directly at the south pole during the period when SUMER is observing.

EIT/LASCO

The EIT/LASCO Eclipse Program can be downloaded from here

These observations are interleaved with the daily synoptic program of the EIT and LASCO instruments. Times given below are accurate. The colors refer to the details of the eclipse program.

SUMER

29 Mar 2006 ≈ 22 h before the eclipse at 10:40 UTC, up to ≈ 4 h before the eclipse, duration 18 h 2 min
Observations of the southern coronal hole(off-limb): Te, ne and velocities in plumes and inter-plume regions; detector B.
29 Mar 2006, ±4 h around the eclipse at 10:40 UTC, duration 8 h 3 min
Observations of the southern polar coronal hole(off-limb with limb calibration): O VI and Ly beta in plumes and inter-plume regions; detector B.
29 Mar 2006 from ≈ 4 h after the eclipse at 10:40 UTC to ≈ 22 h after the eclipse, duration 18 h 2 min
Observations of the southern coronal hole(off-limb): Te, ne and velocities in plumes and inter-plume regions; detector B.

UVCS

27-31 Mar 2006
Participation in JOP 158 in support of the eclipse. The UVCS observations will focus on determinations of O5+ outflow speeds in polar plumes and determinations of the electron density. Plume structures are to be traced out to heights within the LASCO field of view.
