Astronomical Calendar 2015 astronomy events



2015 is full of surprises for observers worldwide. A lot of events will take place this year from occultations to eclipses.
Among these astronomical phenomena, I point out the total eclipse of the Sun on 20 March, and total lunar eclipse of 28 September. On September 28, 2015 will be a total lunar eclipse. I look forward to see the event.
Occultations will take place, 6 in number, between March and Venus, and a lot of conjunctions between the Sun, stars and planets. Conjunction of Mars, Venus and Jupiter on 28 October, I find most interesting.
Another important event is that by February, we will be able to see the dwarf planet Ceres images with the help of NASA's Down device.

Take your binoculars or telescope from the closet, because surely, in 2015 you will not have too many pauses between the events that will unfold in the sky.



Astronomical Calendar 2015 astronomical events.

I have gathered here informations about astronomical phenomena of the year 2015 which took me a lot of time and believe me it was not easy to put them together. I hope you'll find interesting this astronomical calendar.

If you want, you can view astronomical calendar in sections you can see:

-only moon phases
-only perigee / apogee
-only occultations
-only conjunctions
-only comets

In this calendar, further events will occur over time, as asteroids and other objects are evolving in the sky.
Here's how it looks:

02, 03 january 2015 - Quadrantids. Quadrantid meteor shower, get to have up to 40 meteors per hour, usually on 3 and 4 January, but may be visible on 1-5 January. The highest rate of meteors per hour took place in 1932 (80/ hour). The best time for observations is a dark place after midnight. Meteors radiate from the constellation Bootes, close to the North Star.
The source of this meteor shower was unknown until December 2003 when Peter Jenniskens of the Ames Research Center (NASA) found evidence that meteoroids come from 2003 EH1 , an "asteroid", which is probably a piece of a comet which collapsed 500 years ago.

Unfortunately, nearly full Moon will block most brilliant meteors this year. The best time for observing will be from a dark location after midnight.
