Dear SOHO Science Operations Coordinators,

our team has been granted by the observing time for the following 
DOT/LaPalma observing campaign for the time interval August 3-31, 
2007.

- title:  Physical mechanisms driving solar microflares and supergranular
          network dynamics - relevance for coronal heating
- period: 2007.08.03-2007.08.31 (28 days)
- leader : Jan Rybak, (choc@astro.sk)
- proposal: http://www.astro.sk/~choc/open/07_dot/rybak_dot_proposal_2007.pdf
- campaign page: http://www.astro.sk/~choc/open/07_dot/07_dot.html
- campaign approved and granted by the observing time of DOT:
  see the DOT schedule: http://dot.astro.uu.nl/web-schedule2007.txt
- targets: quit sun near the disk center or at mju up to 0.5,
           target selected day in advance according to actual situation on
           the Sun
- time requested: each day from 07:00 till 13:30 UT if possible

Therefore, we would like to ask you for SOHO support of our g-b campaign
using the following instruments:

CDS: all details have been discussed directly with Peter Young in advance.
     We were asking just for the regular operations of the CDS already
     included to its flexible operations of CDS. The VARDYN program was
     run several times already.
     His reply we have got is enclosed to this email.

EIT: CME watch in 195 A channel (or 171 channel). The EIT team was not
     contacted before as we expect that this type of observations is
     nominal for EIT.

MDI: HR magnetograms (1 per minute) +
     HR intesitygrams (higher cadence than 96 minutes)

Operation of our g-b campaign will be performed directly at LaPalma at 
the SST but using my home email address choc@astro.sk. We are aware
that we have to specify the target at least a day in advance.

We see possible conflict with the campaign:

* Aug 5-18      Filament/Cavity-CME-ICME IHY-CIP campaign, 
                CDS/UVCS/TRACE/Hinode-EIS/Hinode-XRT/Hinode-SOT/COMP/SOLARC/
                ProMag/MWA/RHESSI, POC: Terry Kucera

an of course the SOHO actions:

* Aug 12-Sep 09 26m Keyhole (Aug 18-Sep 03 34m Keyhole)
* Aug 28        Spacecraft station-keeping and momentum management 
                manoeuvres
* Aug 30 or 31  Spacecraft roll manoeuvre (timing TBC)

Therefore we understand that there is no change to support our campaign
in the last days of August. Nevertheless we hope there will be a chance
to get some early morning (UT) time for support of our DOT campaign.

According to the previous policy we expect you will specify our request
as a SOHO JOP (+TRACE, +RHESSI). Therefore we have already prepared
a TXT file for it (enclosed to this email).

We have already asked the TRACE team for its support of our campaign
as well (enclosed). Request for the Hinode will be done tomorrow. 
(Similar program but without any g-b support was run on April 12 and 14, 2007, 
during the first SOHO-Hinode campaign).

We do hope that all mentioned SOHO instruments will not be oversubscribed
and at least for some days they will be able to support our DOT
campaign for which we will have perfect LaPalma seeing.

I am looking forward to hear from you about your decision whether SOHO
can support our g-b campaign under specified conditions by EIT, MDI and
CDS instruments. 

With many thanks beforehand

Jan Rybak
