SECCHI Campaign Observations
For at least the first four days of the campaign (May 4th-7th), SECCHI will run its "Active Region/CME Watch" observation sequence. This consists of full-disk EUVI 171 A images every 75 seconds, with the other three wavelengths (195, 284 and 304 A) at a 5 minute cadence. COR1 will obtain pB sequences every 5 minutes. COR2 and the HIs will continue their synoptic observations.
For those instruments that need to select a target for their observations, I suggest AR 10953 as the best choice for now. If you can include AR 10954 in the field of view, that would be great. There may be a need to revisit the choice of target as these regions approach and cross the west limb. With luck, a new region will appear in the next few days.
1. High cadence 304 (spicules) - regular synoptic HI, COR2, and COR1 program - 304 every 37.5 sec (37/38 sec), ICER5 compression - 195 every 10 min, ICER5 - 171, 195, 304 @ ICER4, and 284 @ ICER6 compression every 2 hours - Run only for a couple of days and only if there are no ARs
2. AR and CME watch (2x synoptic cadence & lower compression) - regular synoptic HI and COR2 program - COR1 polarization sequence every 5 min - 171 every 75 sec, ICER5 compression - every 5 min: 195 @ ICER5 compression, 284 @ ICER6 compression, 304 @ ICER4 compression
3. All wavelengths at 2.5 min (ICER5/6 compression) - regular synoptic HI and COR2 program - COR1 polarization sequence every 5 min - every 2.5 min: 171, 195, 304 @ ICER5 compression, 284 @ ICER6 compression
