WASP 13b exoplanet transit (Feb. 22,2012)

Exoplanet Transit Database worldwide Network

HAT P10 / WASP 11b exoplanet transit (Sept. 30,2011)

V 368 Sge summer 2011 campaign, concluded

MMARCH 2011

Started GM UMa observing campaign

I’ll try to determinate some TOM of GM Uma, a shortly followed eclipsing variable star

First photometric run made on March 23, 2011 (duration about 2 hours), very difficult observing conditions with bad seeing

A TOM was expected at 19:59 UT

An elaboration (little forced for great points dispersion for seeing) with Kwee and van Woerden alghorithm shows the

minimum possible at about the same hour (only 0.1 mag magnitude down)

corresponding to HJD = 2455644.335768

First Maxim DL lightcurve, seems linear

Forced elaboration seems to show a little magnitudne down

(great dispersion for terrible seeing!)

Used a B-Block Custom Scientific filter

Parabolic fit of points, elaboration by KW alghoritm and O-C position

of my observation (blue point) in O-C gateway ( only one observation between

1991-today !)

I NEED TO OBSERVE MUCH MORE TOM!, THE FIRST IN UNCERTAIN !

HERE WE GO!

December 2010, we start with observation of stars in Catalogue of H-alpha emission stars in the Northern Milky Way
