MAX MILLENNIUM COORDINATED OBSERVING PLAN # 014

  Participating Observatories | Target of Opportunity | Scheduling Considerations | Follow-Up


TITLE: High Cadence Imaging
AUTHORS:  Haimin Wang ( haimin@flare.njit.edu) BBSO/NJIT (Campaign 1)
Gianna Cauzzi (gcauzzi@arcetri.astro.it) Arcetri (Campaign 2)
Peter Gallagher (ptg@hessi.gsfc.nasa.gov)  RHESSI/GSFC (Campaign 3)
Hugh Hudson (hhudson@taiyan.ssl.berkeley.edu) RHESSI/UCB
Richard Canfield (canfield@physics.montana.edu) RHESSI/MSU
VERSION: 24 July 2002 
SUMMARY: RHESSI is capable of making high-quality hard and soft X-ray movies with a cadence of 2 seconds (half spin) and even down to 10s of ms for intense events, and seeks collaborators at observatories working in other spectral bands (H-alpha, radio, EUV, continuum, ...) who can make observations at similar cadence.

TARGET OF OPPORTUNITY

If there is a region on the disk, or even at the limb, with a good chance of flaring (say at the C5 level or above), the Max Millennium Chief Observer (MM_CO) will send out a "MM#014 High Cadence Imaging Target" message instead of the usual "MM#009 Default RHESSI Target" message.  This then cues all interested observatories to make whatever high cadence observations they have indicated they will make, with this region as the target.  Since such observations can be very resource-intensive, the MM_CO will not declare such a target unless (say) the chance of C5 or better in the next 24 hours is 50% or higher.

This observing program has higher priority than the default plan (MM_OP#009), but lower priority than the major flares plan (MM_OP#003).

Announcements will be made via  the Max Millennium MOTD e-mail list.  To make sure you subscribe to the Max Millennium MOTD list, go to the Max Millennium E-mail and Hypermail page.

SCHEDULING CONSIDERATIONS  

Some observatories can  make high cadence observations only during specific previously scheduled periods.  For this purpose, three time periods haved been identified:
        Campaign 1: May 20 - June 2, 2002
        Campaign 2: August 4 - 12, 2002
        Campaign 3: August 27 - September 6, 2002.
During these periods high cadence observations will be made only if suitable regions are present, as discussed above.

        Campaign 2: August 4 - 12, 2002
        Campaign 3: August 27 - September 6, 2002.
