5 Planets Will Align Over Oregon: Forecast, How To Watch

OREGON — A rare alignment of five planets that won’t be seen again for decades is coming to a peak after the summer solstice when a crescent moon joins the parade in the nighttime skies over Oregon.

If you’re putting skywatching on your weekend agenda, the weather forecast for the Portland area is for mostly clear skies on Thursday night and Sunday night and clear skies on Friday and Saturday night.

Temperatures are expected to be in the low 50s on Thursday night, the high 50s on Friday night, and in the low to mid-60s on Saturday and Sunday night.

The procession of planets — Mercury, Venus, Mars, Jupiter and Saturn, in that order — will be visible just above the eastern horizon during an hour or so before sunrise through the end of the month, according to AccuWeather.

The best date to mark is before 5 a.m. local time on Friday, when a crescent moon joins the planetary parade.

Best of all, the planetary alignment is visible without a telescope, though AccuWeather notes that Mercury may be hard to spot because it’s the dimmest of the planets and will be the lowest in the sky.

For the best chances to see all five planets, try to find a fairly flat open space without trees, buildings and mountains to get in the way.

The last time the five planets lined up was in 2004, and it won’t happen again until 2040, according to AccuWeather.
