Dear colleagues,
I have been able to observe a second (consecutive) eclipse of RX J0909.8+1849, during tonight's run at CBA Belgium Observatory. This has enabled me to determine the orbital period of the system, which is 0.1751d or 4h12m.
This value very well explains the Feb 10.303 UT observation Patrick Schmeer refers to in his vsnet-alert message 4183. He has indeed made an image at the moment of an eclipse.
Clouds have now entered the Belgian skies. I hope someone else will be able to take over on this interesting object ...
Best regards,
Tonny Vanmunster
