* Monitor solar activity as described here. Then look at the respective data gap files, and check for gaps coincident with the flare times. If such gaps exist, contact an operator and ask to replay the data.
+
* Monitor solar activity. The [http://solarmonitor.org Solar Monitor] is a useful tool for this, as are the [http://solar.physics.montana.edu/max_millennium/ Max Millenium] daily solar activity updates.  Changes in solar activity levels may prompt actions such as changes in decimation states, and the current activity level should be taken into account whenever changes are made to the spacecraft program (i.e. spinups, detector changes, etc.)  The [http://hesperia.gsfc.nasa.gov/~schriste/tohbanlive.php Tohban Live] page is also a good starter page that shows GOES activity and spacecraft status info.
-
* Record [[attenuator]] state changes and [[decimation]] state changes, which can be seen in the [http://hesperia.gsfc.nasa.gov/hessidata/metadata/ metadata plots]. For obtaining more exact times via IDL, refer to the [[Tohban Useful Routines]] page. This is also very useful for imaging spectroscopy. Ideally, each major flare would be mentioned along with any changes in attenuator state or decimation state during that time though this is not required.
+
* Monitor the SSR fill level. If the memory is not emptying after the daily pass set, steps may need to be taken to reduce the fill level, including changing the decimation state, changing the collection of nighttime data, or changing detector parameters if one detector is causing the high fill. In rare cases of extremely high activity, data could be deleted by moving the SSR pointers.  Please try to avoid deleting day-before and day-after intervals used for gamma-ray background corrections if this becomes necessary.
-
* Monitor the SSR fill level. Consult with the [[RHESSI operator]] about memory management (possible use of decimation if SSR fill level is too high (>50%).) At times of high activity, it is sometimes necessary to delete data by moving the SSR pointersPlease try to avoid deleting day-before and day-after intervals used for gamma-ray background corrections if this becomes necessary.
+
* Monitor the [http://hessi.ssl.berkeley.edu/ground_systems/hessi_spacecraft_status.html Spacecraft Status page] several times per day.  This page updates once per minute during BGS and Wallops passes.  Parameters that are out of range show up as red or yellow warnings.  There are occasional glitches that cause values to be flagged as errors when they are not -- use judgment as to whether further action should be taken.  (For example, if a parameter is in error consistently throughout a pass, or over more than one pass, then there is an error that needs to be fixed.) Look through past SOH plots to see if the parameter is unusual; send an email to Ops and the Tohban list if action needs to be taken or if you are not sure. Some past issues can be found on the "[[Log of tohban anomalies]]" page.

Duties

The job of the tohban is to help the spacecraft operators at the the Mission Operation Center (MOC), located in the north end of the second floor of the SSL Addition Building, to optimize the science quality of the observations, and maintain the working order of RHESSI's scientific instruments. Tasks include the following.
