Among the finest meteor showers of 2024 closes out the yr this coming weekend.
If skies are clear, look ahead to the Geminid meteors, peaking on the evening of Friday into Saturday, December 13-14th.
The Geminids in 2024
To make sure, the Geminids have just a few strikes towards them this yr. Not solely is it chilly outdoors, however the Moon is close to full, 98 % illuminated waxing gibbous on the bathe’s max.
However do not despair: the bathe hits its most at 3:00 Common Time (UT) on December 14th (10:00 PM EST on the thirteenth) with a max Zenithal Hourly Price of 120 meteors per hour.
This implies the bathe will favor western Europe and North America, a plus. The radiant in Gemini close to the intense star Castor (Alpha Geminorum) additionally signifies that the bathe begins to be energetic within the late night earlier than native midnight.
The supply of the Geminids is none aside from the prolific ‘rock-comet’ 3200 Phaethon. Clearly, one thing intriguing is occurring with this object. On a brief 1.4 yr orbit, 3200 Phaethon appears to blur the road between asteroid and semi-dormant comet nucleus. Japan desires to ship its DESTINY+ mission to 3200 Phaethon in 2028 to get a better look.
The Geminids have placed on a present since 1862, although they appear to have actually taken off in current a long time, surpassing the August Perseids as the very best annual meteor bathe of the yr.
Preventing the Moon
The important thing to seeing any meteor bathe at its finest is to seek out darkish skies and a transparent, unobstructed horizon.
The December Moon sits only a constellation away in Taurus on the bathe’s peak… however have in mind, the bathe can be energetic on the evenings previous to and after the 14th. I plan to pick my observing web site with this in thoughts, and block the Moon behind a hill or tree. Early morning predawn observing will put the Moon decrease to the horizon.
There is a purpose the Moon is at the moment so excessive within the sky: not solely is the Moon close to the December Solstice and occupying the slot that the Solar will maintain in June, however we’re headed in direction of a as soon as each 18.6-year Main Lunar Standstill of the Moon in 2025.
Observing and contributing to meteor bathe science is as simple as watching, recording what you are seeing at a chosen interval, and reporting that depend to the Worldwide Meteor Group (IMO). Consider, a number of different meteor showers are nonetheless energetic in mid-December, together with the November Taurid fireballs and the Ursids, peaking on December twenty second.
For imaging, I like to easily automate the method, and set a wide-field DSLR digicam working on a tripod with an intervalometer to take timed publicity photographs and see what turns up later in submit processing. Purpose the digicam off to at least one aspect of the radiant by about 45 to 90 levels to catch the Geminid meteors in profile.
Do not miss the 2024 Geminids, as a wonderful approach to spherical out sky-watching in 2024.
