This stargazing calendar will help you plan your nights to make the best of the biggest celestial events of 2018. To make the most of your time we recommend that you read our Meteor shower guide, which is filled to the brim with viewing tips and background information about shooting stars.
Also, don’t forget to have a look at our guide: stargazing on the Big Island. The Mauna Kea volcano on the Big Island hosts some of the best telescopes of the world, and a visit to these telescopes is a must if you are into stargazing!
2018 Stargazing Calendar for Hawaii
Stargazing highlights for Hawaii in 2018 are hands down the total lunar eclipse on January 31st, and the Perseids (August) and and Geminids (December) meteor showers. Unfortunately, an almost full moon will make the Quadrantids difficult to observe.
January 3rd: Quadrantids Meteor Shower#
This meteor shower is expected to peak at January 3rd at around 12:00 (noon) HST (Hawaiian Standard Time). This is unfortunately close to the full moon on January 2nd, and makes 2018 a poor year to try to see shooting stars belonging to the Quadrantids.
The light from the (almost) full moon will wash out all but the brightest shooting stars.
January 31st: Total lunar eclipse#
2018 starts truly stellar for stargazers with a total lunar eclipse to close the month of January. If you want to know the ‘how and why’ of lunar eclipses we recommend you read our lunar eclipse 101 guide.
This eclipse starts on January 31st just after midnight at 12:51 am and reaches maximum eclipse at 03:29 am. The total eclipse is visible for 1 hour and 16 minutes between 02:51 am and 04:07 am. These times are for Hilo, if you are watching from other locations the times may be off a few minutes.
Fun fact 1: this lunar eclipse happens during a blue moon, which means that it is the second full moon in a calendar month. A blue moon is pretty rare and happens once every two or three years. This is also the origin of the saying ‘once in a blue moon’.
Fun fact 2: The full moon during eclipse is also near its closest approach to our planet making it appear ~7% larger than an average full moon.
More details on this lunar eclipse can be found here. The next total lunar eclipse visible from Hawaii will be on January 20th 2019.
April 22: Lyrids Meteor Shower#
2018 is a good year to watch the Lyrids. The Lyrids are not the most active meteor shower. With a peak activity of ~18 /hour the expected amount of visible shooting stars is about 5 times lower than that of for example the more active Perseids.
This year’s peak is expected at 08:00 am HST on April 22nd. The moon reaches 1st quarter on that day and sets just after midnight (12:38 am HST). This makes the hours between 01:00 am and 05:00 am (an hour before sunrise) on April 22nd the best time to watch.
May 6: Eta Aquariids Meteor Shower#
2018 is not a good year to catch shooting stars belonging to the η-Aquariids meteor shower. The moon rises before midnight and the waning gibbous moon makes sure the night is moonlit.
If you want to give this shower a try your best bet is to use the hours between sunset (05:48 am HST) and moonrise (just after midnight) on the 6th of May.
May 16-20: Lahaina noon#
Hawai’i is the only tropical state in the USA. This comes with certain perks such as tropical weather and the two times each year when you don’t cast any shadow!
Lahaina noon is a recent (1990) term introduced to give a name to the time of day on which the sun is directly overhead. The term “Lā haina” means “cruel sun” in the Hawaiian language. Lahaina noon is known on the rest of the planet as being at the ‘sub-solar point’, i.e. that point where the sun is standing directly above you and thus you don’t cast any shadow. This is elegantly explained in the following video by vsause (skip to 3:17):
But don’t worry, the sun isn’t that cruel on Hawaii! Unless you are on the hot lava plains without enough water to drink, that is. Better yet, Lahaina moon is a very cool photo opportunity and a time to stop and think about how exactly our earth revolves around the sun. Because of this, Lahaina noon occurs on slightly different times for different places.
On the Big Island, the 2018 Lahaina noon will happen at the following times for these cities:
- Hilo: 12:16 PM (May 16th) and 12:26 PM (July 24th)
- Kona: 12:20 PM (May 18th) and 12:30 PM (July 24th)
- Volcano: 12:17 PM (May 17th) and 12:27 PM (July 25th)
- Waimea: 12:19 PM (May 20th) and 12:29 PM (July 23rd)
June 21st: Summer Solstice and Midsummer Night#
Happy Summer Solstice, today is the first day of astronomical summer! The summer solstice in 2018 takes place in Hawaii at June 21st just after midnight at 12:07 am HST.
The Hawaiian term for summer solstice is “Ka māuikiʻikiʻi o ke kauwela” [source].
Midsummer night is the shortest night of the year, and you could try to make your midsummer night a special one. What better excuse is there for a celebration? Many cultures have festivities linked to the summer solstice, so what about organizing your own midsummer night party or pau hana’s?
July 16-25: Lahaina noon (2/2) #
Lahaina noon is the moment when the sun is standing directly above you. This means that the only shadow you cast is directly below you, and that tall vertical objects. such as for example phone poles and beer bottles, won’t cast a shadow at all!
You can read a more elaborate explanation about the Lahaina noon at the may listing of this event(1/2).
On the Big Island, the 2018 Lahaina noon will happen at the following times for these cities:
- Honolulu, (O‘ahu): 12:37 PM (July 16th)
- Kahalui (Maui): 12:32 PM (July 18th)
- Hilo (Big Island): 12:26 PM (July 24th)
- Kona (Big Island): 12:30 PM (July 24th)
- Volcano (Big Island): 12:27 PM (July 25th)
- Waimea (Big Island): 12:29 PM (July 23rd)
August 12: Perseids Meteor Shower#
2018 is a great year to watch the Perseids!
The Perseids have a broad peak which on Hawaii will be between ~10 am and 10 pm on August 12th. However, you should also be able to see shooting stars belonging to the Perseids meteor shower a few nights before and after the 12th.
The new Moon on August 11 provides optimal conditions for seeing of the Perseids. The nights will be almost completely dark and the moon rises together with the sun.
The best time to look for the Perseids is between midnight and 05:00 am in the early mornings of August 12 and 13, 2018.
If you live on another Hawaiian island you can use the following table to see what are the best times for stargazing the nights between August 10th and August 14th, 2018 To convert these times to your location on Hawaii you should add some minutes depending on how far west you are. For example, 4 minutes for Kona, 7 minutes for Kahului on Maui, and 13 minutes for Honolulu on O’ahu.
|Date||Sunrise||Moonrise||Moon illumination (%)|
|August 10||05:59 am||05:14 am||0.4|
|August 11||05:59 am||06:20 am||0.5|
|August 12||05:59 am||07:24 am||3.8|
|August 13||06:00 am||08:26 am||9.9|
|August 14||06:00 am||09:25 am||18.0|
Note that it takes about 1 hour after sunset to become completely dark. Similarly, the moon will illuminate the sky a bit even before it rises over the horizon. With this in mind you see that the window you have to see shooting stars is small, but longest the days after the peak of the Perseids.
October 21: Orionids Meteor Shower #
2018 is not a good year to look for shooting stars belonging to the Orionids meteor shower.
October’s waxing gibbous Moon sets just before the sun rises and viewing conditions will be far from optimal. You can read more about the Orionids in our 2012 blog post on the meteor shower.
How to best see shooting stars from the Orionids meteor shower
Shooting stars from the Orionids meteor shower are easy to find: just find the Orion constellation, look in its general direction, and relax your gaze.
To find the Orion constellation you should look for the three bright stars in a line that make up the belt of Orion. These stars rise over the Eastern horizon just after sunset and will keep rising towards the east-south-east until they are almost overhead at dawn [how-to guide].
You can read more viewing tips in our meteor shower guide.
November 17: Leonids Meteor Shower#
The Leonids are not a very bright meteor shower, with an expected hourly rate of ~15 during the maximum. The peak of this shower from Hawaii will be November 17th just after noon (12:30 pm).
The moon sets 1.5 hours after midnight in the early hours of November 17, making the hours between 03:30 and 05:30 a good time to try and see Leonids shooting stars. It might be worth it to get up very early this morning to try to get lucky and see some Leonids!
December 14: Geminids Meteor Shower#
The Geminids are one of the three yearly “big” meteor showers with peak rates (again, under perfect viewing conditions) of over 100 / hour. For 2018 this meteor shower will most likely steal the show together with the Perseids!
Luckily for us the Geminids peak activity is spread over at least a few days. If you can’t make it on the early morning of December 14th December you can also try to see some shooting stars a few nights before and after. Make sure to time your stargazing between ~ 1 hour after moonset and ~1 hour before sunrise. We list to sunrise and moonset times for those nights in a table below:
|Date||Sunrise||Moonset||Moon illumination (%)|
|Dec. 12||06:45 am||10:34 pm||28.3|
|Dec. 13||06:45 am||11:24 pm||37.4|
|Dec. 14||06:46 am||–||47.1|
|Dec. 15||06:47 am||12:13 am||57.1|
|Dec. 16||06:47 am||01:03 am||67.0|
Compared to most other showers the Geminids have a radiant that is very high up in the sky: almost straight overhead. The meteors belonging to this shower are often bright and leave trails that can be visible for a few seconds.
December 21: Winter solstice#
This year on Hawaii, the winter solstice will take place on December 21st just after noon (at 12:23 pm HST).
The winter solstice represents the shortest day and thus the longest night on the Northern hemisphere. A solstice is an event that occurs twice each year as the Sun reaches its highest or lowest excursion relative to the celestial equator on the celestial sphere. You can read a more palatable explanation of exactly what a solstice is here.
The Hawaiian term for winter solstice is “Ka māuikiʻikiʻi o ka hoʻoilo” [source].
