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.
