Required poster abstracts for the CEDAR Workshop June 28 - July 02 at the Eldorado Hotel in Santa Fe, NM are due on-line Friday May 22 and the hotel rates at the Eldorado Hotel last until Wednesday 27 May. After that, the hotel will try to sell rooms at a higher rate, especially for the night of the Santa Fe Opera Gala Celebration on Thursday July 01 at the hotel.

Go to the CEDAR wiki site at: http://cedarweb.hao.ucar.edu/ Click on 'Workshops', '2009 Workshop', and 'Accommodations' under 'General Information' for the hotel information or link to on-line booking. If you fail to get a room in time, contact Susan Baltuch at sbaltuch@ucar.edu for possible help.

To submit a poster abstract, click on 'Register', then on '2009 CEDAR Workshop On-Line Registration'. Enter your email if already registered (click on 'Add an abstract'), or register in order to submit an abstract during the registration process.

If you want to present in an individual workshop session, please contact the conveners. In some cases, like the C/NOFS-Jicamarca session described in a following message, materials need to be uploaded on the wiki in advance of the CEDAR Workshop.


(2) Solicit 2-3 slides per speaker at C/NOFs-Jicamarca workshop at CEDAR 2009


From Odile De La Beaujardiere (Odile.delaBeaujardiere@hanscom.af.mil).

Dear Colleagues,

We would like to invite contributions to the C/NOFS and Jicamarca workshop at the upcoming CEDAR meeting in Santa-Fe, Jun 29 to Jul 2, 2009. The sessions will focus on the equatorial ionosphere during minima in the solar cycle as it deals with C/NOFS, Jicamarca and the equatorial regions. (See the full session description in the CEDAR website).

The two sessions on Tuesday June 30 1915-2115 and Wednesday July 01 1300-1500 will be held in a workshop (not AGU) style in which each speaker will be allotted time for a 2-3 slides-presentation, in order to ensure enough time for discussion. To encourage this, at least one of the slides should deal with unresolved issues. Speakers are encouraged to end the presentation with outstanding questions, and possible ways to solve them, rather than a summary of what has been accomplished.

We solicit your participation, and need to receive your 2 to 3 slides by June 24, BEFORE the meeting. We will then group them in a logical order, and intertwine a few selected invited talks within the sessions. You can either upload your slides to the CEDAR Wiki, or send them to us as an Email.

As soon as possible or by June 24, please upload to the Wiki or send to the 3 email addresses below the title and the 2-3 slides of your contribution.

Odile de La Beaujardiere : Odile.delabeaujardiere at hanscom.af.mil

Many thanks,

Koki, David and Odile

PS: Remember: by June 23, to the 3 organizers, 3 slides on how to improve our understanding of the ionosphere-magnetosphere-thermosphere system during solar min in the equatorial regions.


(3) Layered Phenomena in the Mesospause Region (LPMR) Workshop, Stockholm, Sweden, 12-15 July 2009 - abstracts and registrations due 25 May.


From to Jorg Gumbel (gumbel@misu.su.se).

Registration and abstract submission are now open for the 9th International Workshop on Layered Phenomena in the Mesopause Region (LPMR). The workshop will be held in Stockholm, Sweden, on July 12-15, 2009. Registrations and abstracts are due 25 May (less than a week!).

Details about the programme and the location can be found on the workshop website http://www.misu.su.se/lpmr09.

The LPMR goal is to advance the understanding of mesospheric ice clouds and related processes. Workshop topics of particular interest are

- Global observations of NLC/PMC

- Global dynamical coupling processes

- Microphysics and particle charging

- NLC/PMSE particle sizes and shapes

- New lidar and radar developments

- PMSE observations in both hemispheres

- The influx and ablation of meteoric material

- Trends in the mesosphere

More information can be obtained from the workshop website http://www.misu.su.se/lpmr09 or from Jorg Gumbel, gumbel@misu.su.se.


(4) Arecibo call for proposals - due 1 June


From Murray Lewis (blewis@naic.edu).

ARECIBO CALL FOR PROPOSALS

For the trimester starting October 1st 2009:--


(1) The Arecibo deadline for proposals is Monday 1st June, at 11:00pm EST.
(2) A large percentage of the Arecibo telescope time is being used for
   large surveys.  However, we strongly encourage innovative proposals
   that are not classified as surveys.
(3) The 7 dual-polarization channel, 300 MHz BW, "Mock" spectrometers
   are available for all of the ALFA consortia.  For details see
   http://www.naic.edu/~astro/mock.shtml
(4) A partial implementation of a NEW MODE for the Jeff Mock spectrometers
   will be available, which enables all them to be ganged together to
   provide up to 1 GHz of contiguous spectral coverage.  For this call,
   the implemented functionality only supports a choice for the common
   bandwidth of all of the spectrometers.  It will not support a pulsar
   folding mode initially.
(5) A 720-820 MHz receiver will be available for use in the band freed
   up by the analog to digital TV transition.  Proposals are encouraged,
   on a shared risk-basis, subject to the evolution of other occupants
   of the band, and the realized practicality of using it.
(6) The WAPP spectrometer provides an 8-band dual-polarization,
   single-pixel observing capability.  For receivers that support the
   bandwidth, this mode can be used to place 8 simultaneous bands of
   up to 100 MHz bandwidth each within a 1-GHz band as desired. 680
   MHz of contiguous spectrum can be covered without filter roll-off
   effects.
(7) Large proposals are subject to skeptical review after the normal
   science evaluation.  All such proposals in hand will be reviewed
   during the August following their science evaluation.  That
   usually means that large proposals submitted at the June deadline
   may *not* make the next skeptical review.
(8) A policy for consortia follow-up proposals has been included as
   section 5.8 of the web document detailing information about
   Proposals & Policies, from the link:--
   http://www.naic.edu/~astro/proposals/proposal.shtml
Please note that we no longer keep all receivers on the Arecibo
telescope permanently cooled and that the 610 MHz receiver is no
longer available. The use of the S-high, and C-high receivers
will be more restricted, and their use depends on when they are
scheduled in campaign mode.  S-low is generally kept cold.


------------  Arecibo Observing Information --------------------------
Proposals submitted at the Monday, 1st June, 2009 deadline are
for using the telescope in the eight months beginning 1st October
2009 (ie valid for two trimesters).
Proposal submission details, and a web-based cover sheet, can be found
at http://www.naic.edu/~astro/proposals.  A guide for new-users to the
telescope is at http://www.naic.edu/~astro/guide.  Other user-related
information is at http://www.naic.edu/~astro/astronomy.htm.
Radio sources with declinations between about -1 and +37.5 deg are
visible from Arecibo, and can be tracked over the range of zenith
angles between ~1.1 and 19.7 deg.
Available receivers in the (frequency-agile) Gregorian Dome, their
frequency coverage, typical System Temperature, Telescope Gain and
System Equivalent Flux Density (SEFD = Tsys(K)/Telescope_Gain(K/Jy))
presently are:
----------------------------------------------------------------------
Rx-name     Freq[.] coverage     Tsys (K)   Gain (K/Jy)  SEFD (Jy)
----------------------------------------------------------------------
327         312 -- 342 MHz     (50) + Tsky     10.5       >7.5

----------------------------------------------------------------------
To these receivers should be added the 47 and 430-MHz systems in the
Carriage House.
Pulsar, spectral-line, VLBI, and continuum backends are available to
exploit all receivers.  An overview of the present capabilities of the
WAPP backend, the autocorrelation spectrometer used for both
spectral-line and pulsar observing, is to be found at
http://www2.naic.edu/~wapp/
The Arecibo Mk-5A disc-based recorder for Very Long Baseline
Interferometry (VLBI) is available for use with the VLBA, HSA, EVN and
Global networks at all bands up to 10 GHz.  Those wishing to include
the ultra-high sensitivity of Arecibo in their VLBI observations
should submit proposals directly to these networks rather than to
Arecibo, but include special justification for the use of the 305-m
telescope.  The maximum data recording rate at Arecibo is 1 Gbps.
However, HSA observations are limited to a maximum data rate of 512
Mbps.  eVLBI runs with the EVN have been tested successfully up to 512
Mbps.
The Mk-5A system is also available for single-dish baseband-sampled
data recording.
