Triple-Treat SkyWatching This Week!

Wednesday, December 13th, 2017

This week’s night sky offers a solar system triple-treat, with the Geminid meteor shower on Wednesday night/Thursday morning (12/13-12/14) – a close grouping of Jupiter, Mars, and the crescent Moon on Thursday morning (12/14) – and a near-Earth pass of the Geminids’ source, 3200 Phaethon, on Saturday night (12/16).

 

GEMINIDS PEAK – DEC 13/14

The Geminids; so-called because the shower appears to radiate from constellation Gemini; is a typically prolific event, with frequent fireballs and peak rates of dozens of meteors per hour – and the  meteors, themselves, are bright and often leave long trails. This year’s event should be especially fruitful, with a morning crescent moon offering darker skies for better viewing. Spaceweather.com has already reported 40+ fireballs in the past three days, so peak night could be especially exciting. UPDATE: Spaceweather.com reported 475 Geminid fireballs, as of 12/14!

AFM’s MeteorWatch Episode 03 The Perseid’s

Saturday, July 8th, 2017

Perseid’s  Peak night  Aug 11-12

Active from July 17th to August 24th

The Perseids are the most popular meteor shower as they peak on warm August nights as seen from the northern hemisphere. The Perseids are active from July 17 to August 24. They reach a strong maximum on August 12 or 13, depending on the year. Normal rates seen from rural locations range from 50-75 shower members per hour at maximum.The Perseids are particles released from comet 109P/Swift-Tuttle during its numerous returns to the inner solar system. They are called Perseids since the radiant (the area of the sky where the meteors seem to originate) is located near the prominent constellation of Perseus the hero when at maximum activity.

Radiant: 03:12 +57.6° – ZHR: 100 – Velocity: 37 miles/sec (swift – 60km/sec) – Parent Object: 109P/Swift-Tuttle

AFM’s MeteorWatch Episode 02 Southern Delta Aquariids July 12th to August 23rd

Saturday, July 8th, 2017

Southern Delta Aquariids  Peak night  Jul 29-30

Active from July 12th to August 23rd

The Delta Aquariids are another strong shower best seen from the southern tropics. North of the equator the radiant is located lower in the southern sky and therefore rates are less than seen from further south. These meteors produce good rates for a week centered on the night of maximum. These are usually faint meteors that lack both persistent trains and fireballs.

Radiant: 22:40 -16.4° – ZHR: 16 – Velocity: 26 miles/sec (medium – 41km/sec) – Parent Object: 96P/Machholz?

AFM MeteorWatch : Alpha Capricornids

Sunday, July 2nd, 2017

Alpha Capricornids

Active from July 11th to August 10th

The Alpha Capricornids are active from July 11 through August with a “plateau-like” maximum centered on July 29. This shower is not very strong and rarely produces in excess of five shower members per hour. What is notable about this shower is the number of bright fireballs produced during its activity period. This shower is seen equally well on either side of the equator.

Radiant: 20:28 -10.2° – ZHR: 5 – Velocity: 15 miles/sec (slow – 24km/sec) – Parent Object:169P/NEAT
