  1. Full Moon and Mars for Halloween: The Moon rises in the east about a half hour after sunset on Saturday the 31st, depending on your location. That bright orange dot off to its upper right is Mars.

  2. The Ghost of Summer Suns: Halloween is approaching, and this means that Arcturus, the star sparkling low in the west-northwest in twilight, is taking on its role as "the Ghost of Summer Suns."

  3. Comets have been scarce since NEOWISE departed the scene. Not anymore. Suddenly, there are four fresh faces visible from dusk til dawn.

  4. Mars is edging away a bit now from its close approach to Earth, but on the other hand, it rises higher into fine telescopic view earlier in the night.

  5. Mars comes to opposition on October 13th. Although it was closest to Earth on the 6th, it is still at virtually the same distance all week, remaining 22.5 to 22.0 arcseconds in apparent diameter. This is bigger than we will see it again until September 2035.
