[Whi] Two announcements

[whi at mailman.ucar.edu]

Dear Sirs,

Do " broad description of the heliosphere at solar minimum" include
measurements of such global geophysical parameter as fluxes of different
particles measured at Earth surface?

Flux of secondary cosmic rays measured by particle detectors, reflects the
"primary" cosmic ray flux incident on terrestrial atmosphere, which in
turn is directly connected with dynamics of the heliosphere. 
Cosmic ray fluxes measured at minimal Solar Activity will comprise a
benchmark for further physical analysis of solar modulation events (Ground
Level Enhancements, Geomagnetic storms, Forbush decreases) expected during
24th solar cycle).
Particle monitors located at Aragats Space Environmental Center (ASEC) at
altitudes 1000, 2000 and 3200 m, 
(40˚25′N, 44˚15′E; Vertical cut-off rigidity in 2007: 7.1 GV) 
detect charged and neutral components of the secondary cosmic rays with
different energy thresholds and various angles of incidence. ASEC monitors
were equipped recently with new DAQ electronics and software significantly
enlarging its nformation content.

If you are interested to incorporate in WHI observation compign also
fluxes of cosmic rays, please, inform me about further steps to become a
part of WHI,

Thanks,
Ashot Chilingarian,
Head of Cosmic Ray Division,
Yerevan Physics Institute

******************
*1)  SPD/SPA Session at AGU 2008 Joint Assembly, 27-30 May 2008, Fort
*Lauderdale,  Florida
*
*First Results of the Whole Heliosphere Interval
*
*The Whole Heliosphere Interval (WHI) is an international coordinated
*observing and modeling effort to characterize the 3-dimensional
*interconnected solar-heliospheric-planetary system. It begins with
*data originating at the Sun during Carrington Rotation 2067: March 20
*- April 16, 2008.  WHI's science begins with the solar interior and
*extends through the heliosphere and interplanetary space out to the
*heliopause.  WHI is a special campaign period of the International
*Heliophysical Year, and involves the participation of many
*participating observatories and researchers around the world.  A
*"synoptic" set of observations will provide baseline measurements of
*the heliophysical system, while "targeted" observing campaigns during
*the WHI interval will focus on particular sub-regions of the coupled
*heliospheric system and address specific scientific questions via day-
*to-day coordinated observations. This special session will provide a
*broad description of the heliosphere at solar minimum by showcasing
*early results of the WHI campaign.  We invite contributions to this
*session from anyone involved in WHI observations, either targetted or
*synoptic, or modeling efforts.  For further details see:
