Planets, Comets, and Meteors


Check the Observatory's Sky Report for a weekly summary of where the planets are in the sky over Los Angeles.

For a chart showing the planets currently visible in the sky, check here. Note you can change the time and other settings to customize the chart. Times are in Universal Time (subtract 8 hours to convert from Universal Time to Pacific Standard Time).

This simple table for planispheres lists the constellation in which each naked-eye planet – Venus, Mars, Jupiter, Saturn – is located month-by-month through the year 2035.

Rare Mutual Occultations and Eclipses of Jupiters moon's, a list of the best of these events from 2015, can be found on this page. These events occur for only a few months every six years and are intriguing to watch through telescopes of all sizes.

Comet Panstarrs

Comet PANSTARRS C/2011 L4, imaged from the San Gabriel Mountains (near Mt. Wilson) between 4:30 a.m. and 5:00 a.m. on April 19, 2013. The picture shows the comet’s broad, fanlike dust tail spreading for several million miles away from the sun.

Multiple guided exposures were combined, resulting in an exposure of 4 minutes, 30 seconds. A Canon 20Da was used at ISO 1200 through a 5.5-inch diameter f/3.5 Celestron Comet-Catcher Schmidt-Newtonian telescope. (Image by Anthony Cook, Griffith Observatory).

American Meteor Society, LTD: The pioneering meteor astronomer, Charles P. Olivier, started the American Meteor Society, LTD., in 1911. The AMS is highly recommended for the beginning meteor observer.

The International Meteor Organization: Founded in 1988, the International Meteor Organization provides detailed meteor forecast, observing information and meteor shower reports. It conducts extensive worldwide visual, photographic, video, and radio observing programs. The IMO is recommended for advanced meteor observers.
