The next GEOS meeting (Strasbourg, May 14-16) is approaching.
The meeting will be kindly hosted by the Strasbourg Observatory.

I suggest to met on Saturday May 14 at 14.30 in front of the
Observatory. The meeting will start at 15.00 and will close
around 12.00 on Monday May 16.

Here some preliminary details provided by Michel Dumont:

- L'Observatoire nous a réservé un petit amphithéâtre d'environ 40 à 50 places.
Il est très pentu ! Il est équipé d'un vidéo projecteur et j'ai les coordonnées
de la personne à joindre pour avoir la wifi. Cet amphi est juste à côté du hall
d'entrée où se trouve une grande table ronde où nous prendrons les collations
(samedi en milieu d'après-midi, dimanche matin, dimanche après-midi et lundi matin).
La clé sera confiée à Alexandre COIRIER quelques jours avant et il me la
remettra à notre arrivée.

- L'hôtel IBIS Budget est situé juste en face de la gare. Le trajet (à pied)
Hôtel-Observatoire prend 25 min. Un plan de Strasbourg sera envoyé à chaque
participant ayant réservé une chambre. Il est possible d'effectuer ce trajet en tramway.

- Le repas de dimanche midi aura lieu dans un restaurant alsacien typique
très proche de la cathédrale; le trajet Observatoire- Restaurant est aussi
voisin de 25 min. Il y aura deux menus possibles.

The announced participants are:
Roland Boninsegna, Jacqueline Vandenbroere, Ennio Poretti, Stephane Ferrand,
Michel Dumont, Merce Correa, R. Marcos, Reinhold Auer, Anton Paschke,
Josep Vilalta, Jean-Francois Le Borgne, Juan Fabregat, Francesco Fumagalli.

***   Other participants are welcome !!!  ***
***   Please contact Michel Dumont as soon as possible ***

Details about the payment of the stay at the hotel (2 nights) and the
coffee-breaks will be given soon.

Only a few talks have been submitted so far:

Ennio Poretti - The GEOS observational insights into the Blazhko effect
Josch Hambsch - Recent studies of several RR Lyr stars with Blazhko effect
Josch Hambsch - 5 years Remote Observatory Atacama Desert (ROAD)
Jacqueline Vandenbroere - Les correlations entre les caracteristiques des RRab
Michel Dumont - Variations a faible amplitudes dans les courbes visuelles

*** I kindly ask you to provide other contributions ***

We have to discuss about the GEOS participation to the BAV meeting
(Hamburg, Sep. 17-18).

The programme will be refined and updated in the next weeks.

The GEOS Annual Meeting will be held at Strasbourg Observatory during the Pentecost weekend.

 

It will begin Saturday, May 14, 2016 at 14h and ends Monday, May 16 at 12h.

 

Strasbourg is a tourist town and you have to book hotel rooms as soon as possible.

 

Please, book your room now  for 14-15 May and 15-16 May nights with DMT,  stating clearly if the room is for ONE or TWO persons!

 

A tour operator is responsible for reservations at a modest price.

GEOS members
- to register to the Conference and
- to propose  talks
at the site  http://rr-lyr.ast.obs-mip.fr/capas2012/index.fr.php

The detailed agenda of the GEOS meeting is now as follows :
