On 23 August 2011, a radiation- and age-induced hardware anomaly altered the operational state of SWICS, causing an increased level of background to appear in the heavy-ion time-of-flight measurement and creating an instrument that best measures composition in an Energy/charge–Energy mode. To understand and characterize this background, SWICS data delivery was suspended while various alternate instrument settings were tested and a new model for data recovery was developed. The ensuing new operating mode of SWICS is now called ‘SWICS 2.0’, indicating that it operates as a new and different instrument, delivering a different set of data products than were available previously. SWICS 2.0 data are now available from 1 June 2012 to present day, and SWICS continues to make heavy ion measurements that are not available from any other solar wind composition instrument in flight today.

In addition, the SWICS proton measurements, which are captured in a separate instrument channel and were unaffected by the hardware anomaly, are now delivered at 12-minute resolution for the entire duration of the SWICS investigation.

The data, release notes, and usage guidelines can be found at http://www.srl.caltech.edu/ACE/ASC/level2/index.html, and a data products table can be found in ACE News #177 http://www.srl.caltech.edu/ACE/ACENews/ACENews177.html.

Session on Waves in Outer Solar System Plasmas at US National Radio 
Science Meeting (URSI) 6-9 January 2016

From: Bill Kurth (william-kurth at uiowa.edu)

This session seeks papers on radio and plasma waves in outer solar 
system plasmas, including the solar wind, interstellar medium, outer 
planet magnetospheres, and the solar wind interactions with planets or 
other bodies in the outer solar system.  Papers based on observations, 
theoretical treatments, or modeling are welcome. Papers driven by 
Voyager, Cassini, Galileo, and MAVEN observations are appropriate.

Session Chairmen:  Bill Kurth (william-kurth at uiowa.edu), Bob Ergun 
(ree at lasp.colorado.edu)

The deadline to submit abstracts to the US National Radio Science 
Meeting in Boulder, Colorado (6-9 January 2016) has been extended to 
Sunday, 27 September at 11:59 PDT.

The website for the meeting, including registration and abstract 
submission is: www.nrsmboulder.org

Look for "Waves in Outer Solar System Plasmas" in the drop-down list of 
sessions during the abstract submission process.

RHESSI Science Nuggets in September

From: Hugh Hudson (hhudson at ssl.berkeley.edu)

No. 262, "Fine Structure in Flare Soft X-ray Light Curves," by Brian Dennis and Kim Tolbert: A tool that we’ve had since 1976 now gives us surprisingly precise new information.

No. 261, "Photospheric Electric Fields and Energy Fluxes in the Eruptive Active Region NOAA 11158,” by Maria Kazachenko. Flares need magnetic energy; we can now measure its arrival as Poynting flux across the solar photosphere.

No. 260, “RHESSI and General Relativity,” by Bill Thompson and Hugh Hudson. General-relativistic corrections to RHESSI source positions.


See 
http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets

listing the current series, 2008-present, and

http://sprg.ssl.berkeley.edu/~tohban/nuggets/ 

for the original series, 2005-2008.

We publish these at roughly two-week intervals and welcome contributions,
which should be related, at least loosely, to RHESSI science.
