What is the star or planet which is the brightest object in the UK night sky at ESE 30deg?

Watching from near London at 2:30am (meridian, 0.1deg long, 52deg lat) its East South East, moon is a due East and almost 10 deg lower. Moon will get closer to it and get higher as the night goes on. Guess its magnitude is @ -2.5, but it can't be Venus as isn't that always the "morning star" ?What is the star or planet which is the brightest object in the UK night sky at ESE 30deg?If it is in the east and south at 2 a.m. then it could be a star or the planet Jupiter.

At present Venus should be in the west right after sunset.



Venus is the brightest object in the night sky other than the moon. It is so bright that it can be seen even in full daylight (If you know exactly where to look).



One thing that distinguishes Venus from a star is that you can see an actual area of surface instead of only a point of light like that of a true star (easier with binoculars). Because of this, Venus does not “twinkle” the way stars do. Twinkling is caused by Earth’s atmospheric disturbance of the points of starlight.



Venus can only be seen at night within 48 degrees angle or less from the rising (or setting) sun because its orbit is closer to the sun than Earth's. This means that at night you can only see Venus within a couple hours of sunrise or sunset.



If you see Venus just before dawn, it is moving away from the Earth as it travels in its orbit. See it just after sunset and it's approaching us.

You're probably looking at Jupiter. It's far too late for Venus.What is the star or planet which is the brightest object in the UK night sky at ESE 30deg?It's the planet Jupiter.What is the star or planet which is the brightest object in the UK night sky at ESE 30deg?
It's the planet Jupiter.What is the star or planet which is the brightest object in the UK night sky at ESE 30deg?yes its jupiter.



try this next time. it helps alot. be sure to set your location though.

While Sirius is the brightest start in the northern hemisphere,most of the inner planets will have a lower magnitude (i.e. brighter) at various times of the evening,year, planetary cycles,etc. on most any night,the visible planets, venus,mars,jupter , mercury and saturn will be the brightest.



Tho there are several websites that give great weekly previews of highly visible objects,like

sadly,most of them, that I see are very biased to the USA or North American viewpoint and time frames.



2:30am? eek! If I'm up at that hour there is some serious server problem ,with purple alert alarms going off.What is the star or planet which is the brightest object in the UK night sky at ESE 30deg?
Is it always in the same spot? Does it disappear in the morning? Guessing it's a streetlight.
If it is in the east and south at 2 a.m. then it could be a star or the planet Jupiter.

At present Venus should be in the west right after sunset.
