"Venus (the brighter object at upper left) and Jupiter approach a twilight conjunction in late June 2015. The two planets meet in the morning sky this month." Astronomy Magazine, August 2025, p. 28. - Alan Dyer

The Month At-A-Glance
A calendar displaying the daily astronomical events.

(Times are Mountain Daylight Time (MDT/MST) unless otherwise noted. Times will vary slightly depending on your location.)

Planetary Highlights for August "The longer nights of August beckon with several treats this month. Saturn and Neptune undergo their second conjunction of the year, appearing together in a low-power telescope eyepiece. Telescopic observers also get two shadow transits of Titan across Saturn. Early risers enjoy a spectacular conjunction of the two brightest planets in the sky, Venus and Jupiter, on Aug. 12, the same day the Perseid meteor shower peaks." Astronomy Magazine, August 2025, p.28.
	Mercury Is stationary on the 10th. Mercury is at greatest western elongation (19°) on the 19th. Mercury rises at 6:09 a.m. on the 1st and about 5:30 a.m. by month's end. Mercury is visible about 30 minutes before sunrise just above the eastern horizon after the first week of the month. Mercury moves from the constellation of Cancer into Leo shining at magnitude 0.7 on the 15th.
	Venus Rises about 3:04 a.m. on the 1st and about 3:52 a.m. by month's end. Look for Venus to the southeast about an hour before sunrise. Venus moves from the constellation of Gemini into Cancer shining at magnitude -3.9 on the 15th.
	Earth N/A.
	Mars Sets at 10:15 p.m. on the 1st and about 8:58 p.m. by month's end. Look for Mars to the west in the evening. Mars is in the constellation of Virgo shining at magnitude 1.6.
	Jupiter Rises at 3:46 a.m. on the 1st and about 2:13 a.m. by month's end. Look for Jupiter to the southeast about an hour before sunrise. Jupiter is in the constellation of Gemini shining at magnitude -1.9.
	Saturn Rises at 10:28 p.m. on the 1st and about 8:22 p.m. by month's end. Look for Saturn low to the east late in the evening. Saturn is in the constellation of Pisces shining at magnitude 0.7.
	Uranus Rises at about 1:01 a.m. on the 1st and about 8:20 p.m. by month's end. Look for Uranus to the south before sunrise. Uranus is in the constellation Taurus shining at magnitude 5.7.
	Neptune Rises at 10:24 p.m. on the 1st and about 10:24 p.m. by the month's end. Look for Neptune low to the east late in the evening leading Saturn by just a few of minutes all month. Neptune is in the constellation of Pisces shining at magnitude 7.7.
	Dwarf Planets
	Ceres Is stationary on the 15th. Ceres rises at 11:51 p.m. on the 1st and about 9:55 p.m. by month's end. Ceres can be spotted low to the south after midnight. Ceres is in the constellation of Cetus shining at magnitude 8.4.
	Pluto Rises at 7:57 p.m. on the 1st and about 5:53 p.m. by month's end. The best time to spot Pluto is around midnight when it is highest in the sky to the south. Pluto is in the constellation of Capricornus shining at magnitude 15.1. As always, good luck at spotting Neptune, Ceres and Pluto, a large telescope and dark skies will be needed.

Astronomical Events

	Meteor Showers The Northern Delta Aquarids [meteor shower] extends from July 16 to September 10. Maximum occurs on August 13. The hourly rates reach a high of 10. The Perseids meteor shower is generally visible between July 23 and August 22. Maximum occurs during August 12/13. The hourly rate typically reaches 80, although some years have been as low as 4 and as high as 200. The meteors tend to be very fast, possess an average magnitude of 2.3 and leave persistent trains. "A FULL MOON Aug. 9 significantly affects the visibility of Perseid meteors. By Aug. 12, the night of the Perseids' peak, the Moon rises around 10 P.M. local daylight time and remains up the rest of the night, just as the shower's radiant in Perseus is climbing higher in the sky. But all is not lost the Perseid meteor shower carries some of the brightest meteors, which are always visible even with moonlight. You can improve the visibility of fainter meteors by traveling to higher altitudes (above 5,000 feet), where a thinner atmosphere reduces the scattered light of the Moon, rendering the sky darker. Even so, observed rates this year will be well below the advertised peak. Set your expectations at a dozen per hour. The Perseids are active from July 17 through Aug. 24. The earlier part of the shower occurs under a dark Moon. On Aug. 1, for example, the First Quarter Moon sets around midnight. The radiant reaches a respectable 50° in altitude by 4 A.M. local daylight time. The moonless skies diminish by nearly an hour each day. The Perseids are associated with Comet 109P/Swift-Tuttle, which last reached perihelion in 1992 and returns again in a century." Astronomy Magazine, August 2025, p.29. Meteor Shower Radiant Report For more information about Meteor Showers, visit Gary Kronk's Meteor Showers Online web page. Meteor Scatter (or Meteor burst communications) - "is a radio propagation mode that exploits the ionized trails of meteors during atmospheric entry to establish brief communications paths between radio stations up to 2,250 kilometres (1,400 mi) apart." Tune your shortwave or your HF amateur radio to 54.310 MHz SSB and see if you can hear any pings. Try other frequencies as well... 6m FT8 digital - 50.313 Mhz & 50.276 Mhz, JP-65 digital mode and the carrier frequencies of the lower VHF bands for TV channels 2, 3 & 4. Meteor Rx How-To by Terry Bullett (WØASP)
	Comets Comet C/2024 E1 (Wierzchos´) is passing through the constellation of Hercules this month shining around 12th magnitude, so a 10 inch scope or greater and dark skies will be needed to view it. For information, orbital elements and ephemerides on observable comets, visit Observable Comets. For more information about Comets, visit Gary Kronk's Cometography.com webpage.
	Eclipses Solar Eclipses No solar eclipse activity this month. Lunar Eclipses No lunar eclipse activity this month.
	Observational Opportunities Look for Mars in the evening to the west. Look for Pluto to the south. Look for Saturn, Neptune and Ceres in the late evening and early morning to the south-southeast. Look for Uranus, Jupiter, Venus and Mercury in the morning to the east.
	Asteroids (From west to east) Vesta is in the constellation of Libra. Pallas is at opposition on the 7th in the constellation of Delphinus. Julia is at opposition on the 11th in the constellation of Capricornus. Hebe is at opposition on the 26th in the constellation of Aquarius. Information about the Minor Planets can be found at the Minor Planet Observer website.
	Ocultations Information on various occultations can be found by clicking the IOTA logo.
