As 2013 draws to a close, we once again cast our thoughts to all things astronomical for the coming year. For the last half decade, I've been constructing this list of all things astronomical for the following 365 days, lovingly distilling the events transpiring worldwide down to a 101 "best events of the year." Here are the top picks for 2014!

Ground Rules, Selection Criteria, Caveats, etc.
Events selected run the gamut from conjunctions and eclipses that are visible worldwide or over a good swath of the planet, to asteroid occultations of stars that are only visible along a thin path along the surface of the Earth. Geocentric conjunction times for occultations are quoted. Generally, only conjunctions involving bright stars, planets & the Moon are noted. The intent of this list is to bridge the gap between the often meager "10 Best Astronomy Events of 2014" listicles that make their rounds this time of year and the more tedious laundry lists of Moon phases and wide conjunctions.
As always, we look at the coming year with an eye out for the astronomically curious and the bizarre. Times are quoted in Universal Time (UT) using a 24-hour clock, which is identical to Greenwich Mean Time (GMT) and Zulu for those in the military.
Some caveats as to how selections were made:
-To make the cut, asteroid occultations must have a rank of 99 or greater, and occult a star brighter than +8th magnitude.
- We only selected major annual meteor showers with a Zenithal Hourly Rate (ZHR) projected to be 20 or greater.
- Only lunar occultations of planets and bright stars are listed.
- Solstice seasons where the International Space Station reaches full illumination are approximate; the ISS gets boosted periodically, and therefore it's impossible to project its precise orbit months in advance.
- Comets come and go. The comets included on this list are some of the "best bets" that are forcasted to reach binocular visibility for 2014. A big bright one could come up and steal the show at any time!
This list was meant to "whet the appetite" for what's coming to skies worldwide in 2014 with a succinct rapid fire listing by month. Where an online resource exists that expands on the event, we linked to 'em. A full resource list, both paper and cyber, is given at the end of the post. Print these events, post it on your refrigerator and/or observatory wall, and expect us to feature many these fine events on Universe Today in the coming year!
Some notes on 2014:
2014 sees Mars reach opposition in early April, which is sure to be a highlight as we head towards an exceptionally close opposition in 2018.
The month of February is also missing a New Moon, which last occurred in 1995 and won't happen again until 2033. February is the only calendar month which can be missing the same moon phase twice!
We're also coming off a profoundly weak solar maximum in 2014, though as always, the Sun may have some surprises in store for solar observers and aurora watchers worldwide.
The motion of the Moon in 2014 is headed towards a "shallow" year in 2015 relative to the ecliptic; it will then begin to slowly open back up and ride high around 2025.
2014 also contains the minimum number of eclipses that can occur in one year, 2 solar and 2 lunar. And while there are no total solar eclipses in 2014, there are two fine total lunar eclipses, both visible from North America.
