RHESSI Tohban report, 22-Aug-2007 to 29-Aug-2007 Pascal Saint-Hilaire, shilaire@ssl.berkeley.edu 1. Solar Activity After a streak 3 short flares on Aug. 24 (the highest being a C-flare, which RHESSI missed), the GOES lightcurves have pretty much flatlined somewhere below the A0.3 level. AR 10969 is still smack in the middle of the solar disc, but is being very well behaved. How many GOES flares occurred? Flares above B, C, M, X class were 4 1 0 0 RHESSI flare list contains 0 over the time range 21-Aug-07 28-Aug-07 No overlapping RHESSI flares to count, sorry 2. Memory management SSR memory usage is typically below 15% at the end of the day's passes. Decimation is always NORMAL/ACTIVE, no data are taken during RHESSI night. 3. Data Gaps The data files for one of the data gaps mentionned by Amir last week are there, but the Observing Summary plots shows there are none: 2007-08-21T02:35:00.000 -- 2007-08-21T08:30:00.000 21300.000 Same goes for: 2007/08/22 ~08:00-12:30 2007/08/22 ~14:30-16:00 2007/08/23 ~13:30-18:00 2007/08/25 ~06:30-09:45 2007/08/28 ~11:00-14:00 It seems the correpsonding vc3 data have not been processed yet. 4. Misc. a. No SOH plots after 2007/08/22 from http://sprg.ssl.berkeley.edu/hessiops/state-of-health/2007/welcome.html b. RHESSI observing times at solarmonitor.org do not work since 2006/09/23. http://www.solarmonitor.org/full_disk.php?date=20070829&type=smdi_maglc It seems these relied on previously SSL web-published ephemeris in ASCII, that no longer are. (http://sprg.ssl.berkeley.edu/~hhudson/goes_hessi_plots/ is still working, though) c.The State-of-Health plots at http://sprg.ssl.berkeley.edu/hessiops/state-of-health/2007/welcome.html indicate the year as being 2006, instead of 2007. d. No new GOES data in SSWDB at SSL since 2007/06/27. This is because it is not present at sohoftp.nascom.nasa.gov, the site we mirror it from. Let's wait and see if they can get their act together. In the meantime, the data is still available from the SDAC. e. Cold plate temperature 88K f. Waldheim "hiccup". No data loss is expected. 5. Next Tohban: Iain Hannah
