It\u2019s best viewed in early evening, standing highest around 10 P.M. local daylight time, when it is more than 80\u00b0 above the southwestern horizon.<\/p>\n<p class=\"wp-block-paragraph\">You\u2019ll find NGC 7331 glowing at 10th magnitude just 4.4\u00b0 north of 3rd-magnitude Matar (Eta [\u03b7] Pegasi). Stretching some 11\u2019 long and 4\u2019 wide, this lovely galaxy has a large, bright nucleus with no bar, surrounded by delicate spiral arms. Even though the galaxy is nearly edge-on, larger scopes will allow you to see exquisite detail in those arms.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">We see NGC 7331 from a distance of 40 million light-years, but it\u2019s not the only galaxy in sight. Again, a larger scope (11 inches or more) is needed, but will reveal at least three of the Deer Lick Group\u2019s other members, collectively called the \u201cfleas\u201d because they appear much smaller than NGC 7331, clustering around it. But these aren\u2019t smaller dwarf galaxies swarming a larger central body \u2014 instead, the fleas are not physically associated with NGC 7331 at all, but lie far beyond it, at distances some 290 million to 370 million light-years\u00a0away.<\/p>\n<p class=\"wp-block-paragraph\"> Sunrise: 7:16 A.M. <br \/>Sunset: 6:13 P.M. <br \/>Moonrise: 3:32 P.M. <br \/>Moonset: 1:11 A.M. <br \/>Moon Phase: Waxing gibbous (73%) <br \/>*Times for sunrise, sunset, moonrise, and moonset are given in local time from 40\u00b0 N 90\u00b0 W.

Credit: Astronomy: Roen Kelly<\/p>\n<p class=\"wp-block-paragraph\">The best time to do some meteor-watching is between 2 A.M. local daylight time and dawn, as the radiant in Orion rises higher and the Moon has already set. Around 5 A.M., the Hunter stands above the southern horizon, his famous three-star Belt easy to find. Meteors in the Orionid shower appear to originate just to the upper left\u00a0 (northeast) of Betelgeuse, the bright red giant that serves as one of Orion\u2019s shoulders. Once you\u2019ve found this star, cast your gaze some 40\u00b0 to 60\u00b0 to either side, away from it \u2014 that\u2019s where you\u2019ll see meteors with the longest trains.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">This year\u2019s shower is expected to produce some 15\u201318 meteors per hour in the early-morning hours. And if you aren\u2019t able to get out in the morning, you can try again late tonight after Orion rises and overnight into tomorrow morning. Even though the peak has passed, meteor rates will still be higher than the sporadic six or so per hour that are visible even without any showers active.\u00a0<\/p>\n<p class=\"wp-block-paragraph\">Alison Klesman\u00a0is senior editor of\u00a0Astronomy\u00a0magazine.
