||Cloudbait Observatory Home|
Welcome to Cloudbait Observatory, located under the dark skies of the central Colorado Rocky Mountains.
Here you will find details about the observatory itself, its history (and my own as an amateur astronomer), the science I conduct here, and a collection of images I've made. Details of the instrumentation I use and some of the tricks I've developed to make it work well are given.
I am very interested in instrumentation, and much of what I design is freely available to anyone interested. Details about some of these projects are posted on this site.
I also enjoy both history and travel, and seek out places of special astronomical significance. The section on archaeoastronomy details some of the places I've been, and the historical astronomical sites I've explored.
On October 6, 2014, a very bright fireball exploded over Colorado. It was caught on two of our Colorado cameras, and the trajectory determined. Details of this event are here.
On September 2, 2014, a Russian spy satellite decayed over Colorado. This decay produced a slow, bright fireball seen from New Mexico to South Dakota. It was caught on two of our Colorado cameras, and the trajectory determined. Details of this event are here.
There was a beautiful pre-dawn conjunction in August. Venus and Jupiter were close for a couple of weeks, separated at one point by only half a lunar diameter. As they pulled apart, they were joined by a fine crescent Moon. Some images of this event are here.
There was a bright fireball over northern Colorado on October 23. This exceptionally long meteor (13 seconds) occurred at 9:19 pm, and was widely witnessed. A report on it can be seen here. If you saw it, please report it.
Comet C/2011 L4 (PANSTARRS) has faded from easy view. It was a naked eye comet when it passed closest to the Sun in March, and remained a bright telescopic object for several months afterward. Images from Cloudbait can be seen here.
On June 5, 2012, Venus passed across the face of the Sun, a transit observable over much of the world. Despite marginal weather conditions, I was able to image this event from Cloudbait. A report is available here.
On May 20, 2012, the southwest experienced an annular solar eclipse. I traveled south to New Mexico to place myself on the eclipse centerline. A report is available here.
There was a total lunar eclipse on 10 December 2011. From central Colorado, the Moon was just entering totality at sunrise, providing an interesting photo opportunity. A report and some images are available here.
On September 2, 2011 the Cloudbait allsky camera captured three sets of sprites. Sprites are poorly understood electrical atmospheric phenomena that occur very high (50-100 km) above thunderstorms, and which are triggered by lightning below. Images of the captured sprites can be seen here.
On the morning of March 18, 2007, Pluto passed in front of a dim star, casting the shadow of the planet across North America. Examine the data collected from Cloudbait.

There have been no fireballs reported in the last seven days.
Meteor and fireball activity is high during the second half of the year. See how activity changes over the year.
If you live in Colorado or the surrounding states, and have recently seen a very bright meteor, please report it here. We continue to investigate bright fireballs, and now have an extensive network of allsky cameras in place to supplement witness reports. If you just witnessed a meteor and are curious if it was recorded from central Colorado, try the new real-time meteor log which lists all events captured by the Cloudbait camera as they occur. These events are normally processed into the main database each morning.

The material here is necessarily graphics intensive, but I've done my best to optimize the images so that download times should be reasonable even with slow network connections.
