On Nov. 14, 2007, a star in the constellation Puppis suddenly became visible in binoculars.
A nova visible in good binoculars was spotted July 7, 2012, by observers in Japan.
Photometric recordings of Pluto passing near stars, as on the night of May 11-12, 2007, could reveal if it has a ring system.
Pluto will pass extremely close to an 8.7-magnitude star on September 27, 2007; observers should monitor the star's brightness electronically.

On Tuesday morning, August 21, 2007, observers across much of North America should watch for a possible occultation by asteroid 146 Lucina's satellite.
A very old dust trail from Halley's Comet could enhance this meteor shower on May 6, 2007.
An unexpected meteor burst was detected on the night of September 8-9. Bill Cooke of the Marshall Space Flight Center is urging meteor watchers to see if the activity continues on the night of September 9-10.
Both Pluto and the star are 14th magnitude, but observers with big telescopes and sufficient video capability should try to record this important event.
A huge, remote asteroid could briefly blot out a faint star in Gemini on February 10-11, 2008.
During January 2009 a faint star in Cepheus will fade, as it does every five or six years, when "something" goes in front of it.
Our February 2003 AstroAlert test went very well. Here we report on what we learned, thanks to the enthusiasm and dedication of the test's participants.
Late Monday night, October 6-7, 2008, a tiny asteroid will enter Earth's atmosphere over Sudan, creating a spectacular explosion in the night sky.
The year's best grazing occultation in North America occurs on June 19-20, 2007, when the waxing crescent Moon covers Regulus (Alpha Leonis).
A suspected dwarf nova is undergoing its first observed outburst and had reached 9th magnitude as of September 5, 2007. More observations are needed.
In February 2003, Sky & Telescope and the SuperNova Early Warning System (SNEWS) conducted a test of the AstroAlert system. Here's what it looked like.

The countdown has begun for this important occultation of a 15th-magnitude star by Pluto, due to occur on Sunday morning, March 18, 2007.
