The SOHO satellite, lost in late June, has been located, but it is still not operating properly. Chances are slim that it will ever again return useful data. Images obtained before the satellite was lost showed two more sungrazing comets heading toward the Sun.
Comet Meunier-Dupouy passes opposition and enters the evening sky while Comet Linear stays some distance north. Periodic Comet Giacobini-Zinner brightens in our evening sky; it orbits the sun every 6.6 years.

Comet hunting notes: While comet hunting, I've always recorded the number of meteors I happen to observe passing through my field of view. On June 16 of this year I recorded my 10,000 telescopic meteor. The span of time was 6314 hours over the course of 23 years. The number of meteors I see per hour in the morning sky averages 1.9 while the evening sky averages 0.9. I also record the number of artificial satellites I see. The hourly rates for these has increased, and now exceeds the meteor rates. I made my 10,000th satellite sighting about a year ago.
