We always are waiting for summer hollidays. Spare time, good weather, friends, and when it comes to astronomy, its very important the fact of we have the possibility of enjoy of a bunch of nights to observe, take pictures, maybe check the equipment or simply fix it after a software crash, for instance.
Well, all this is in theory, because this has been one of the worst summers that I remember in many years, astronomicaly speaking, of course.
During this ended august we have had barely few good nights from wanning moon to crescent one.
In return, soft daily temperature and almost no news about fires at the countryside.
As a result, I could only mesure a variable star and the position of two asteroids.
Regarding the fotometry of the variable star, here you have the curve.
As you can see, the seeing wasn´t very steady so the curve, despite being very obvious, it was a little bit shaking too.
Anyway, because the sort period of this star (0.068983 days), a Delta Scutii type, I "only needed" three nights in order to achieve data to get the phase.
AX Tri is placed in the Triangulum constellation, a SXPHE, coordinates 01 31 49.23 +35 13 23.9 and It almost shrinks one magnitude. Here you have more info.
Here is a phase of another variable star that I´ve been collecting along the past spring:
This is an eclipsant type EW since it has two minimums, a big one and a small one.
This kind of stars are composed by two stars, one possibly big or at least very bright and the other one smaller or darker. When one of them passes in front of the other in our line of sight, then there is an eclipse. When the smaller or darker eclipses the brighter one, the minimum falls almost one magnitude and when the brighter star is in front and the darker one is behind, the oscillation is minimum.
