CalSKY

I recently signed up with CalSKY for their free online service. CalSKY provides observing data, email alerts (Aurora, comets, satellite passes, including sun/moon transits, supernova, and more), and other very useful data online. I signed up for several email alerts. On Thursday, 19 May, I received this email (only a small portion shown):

The email said I could expect a transit of the moon by the Hubble Space Telescope (HST). I clicked several of the links in the email and got lots of useful information, such as this one showing how the HST would cross the moon:

There was even a map showing where the centerline of the transit was (close to me). The email included a link to save the event to iCal or Outlook. I clicked that and a file was downloaded to my computer. I had to remove the ".vcs". extension in the filename in order for iCal to load the event. But once I did that and double-clicked the file, iCal imported the import and it immediately appeared on my iPhone:

I video recorded the moon with my Nikon D7000 DSLR mounted at prime focus of my Meade 8" LX200-ACF. For more on the attempt to capture the HST crossing the moon, see the 20 May 2011 entry on the Reports page on my Cassiopeia Observatory web site. Was I successful? You'll have to read the report.

I am sure I will be using CalSKY a lot in the future and their email alerts are already proving to be very useful. Check out CalSKY for yourself and I'm sure you will immediately sign up. Remember, the basic service which includes all I've mentioned here is FREE.
