HAA Skywatch

From our Facebook page, the Hubble team with NASA and ESA are sponsoring a contest to find some of the hidden treasures in the vast stored archive of the Hubble images collected over the past 22 years. It actually consists of 2 parts. First is to find things that hasn't been found by conventional processing or the original science team (they may have been looking for other things). The second part is to use some free tools that have been made available to process images and submit them. You can work on one or the other task.

What I found interesting is that a professional tool (FITS Liberator) produced by PhotoShop for the Hubble team has been made into open source (free) for participants to use. It's already a powerful and useful package, but making it open-source, many programmers can contribute to make it even better. And the beauty is that you can use it without having to purchase PS. Now you can have a powerful tool designed specifically for astro-photography for processing your own images.

Prior to the contest, there were amateurs who scoured the archives looking for interesting things and making significant discoveries (like comets, supernova, galaxy collisions, etc) that hadn't been seen or recognized by the original science team. But there are huge quantities of images which haven't been looked at. This contest gives regular amateurs like you and me a better starting point for us to get into the "game" (more tools, info and help). Amateurs from all over the world are getting into this project - and you can too!

Upcoming transit of the Space Station across the disk of the Sun
About 1:20 PM on Monday afternoon.

If you have a PST or a solar filter, or even some welder's glass, you
can use the same precautions as for an eclipse to see the silhouette of he Space Station against the disk of the sun.

The map shows the ground track of the event, for the center of the shadow path.
At a distance of 350 km, and about a quarter degree, you will see some of it
even if you are as much as 3 km off track.

The other thing to keep in mind is that the orbital predictions for the ISS are
not very accurate. Wish we could do more.
Crossing the disk of the moon, of course, is a naked-eye event you don't need any
precautions for.

In honour of this month's speaker's topic (March Madness) and being related to the Messier Marathon which is attempted by many amateur astronomers, here's an interesting link. March/April is considered to be the most favourable time to attempt to view all 110 Messier objects in a single evening. Considering the cool weather for our latitude and the poor viewing conditions we've had over these past many months, the odds appear to be against us to having a good night to attempt this.

However, you can "do" the marathon from the comfort of your own home on Sun April 1, 2012. The Virtual Telescope in conjunction with GAM(Global Astronomy Month) and Astronomers Without Borders, is holding a Messier Marathon Night. They will use various remote, robotic telescopes to attempt to view all 110 Messier objects in a single night.

A small team of HAA'rs visited a Cub pack near the north end of Oakville on Leap Day (Feb 29) to teach astronomy to about 25 enthusiastic kids. This is the second time in recent history that the HAA brought astronomy to a group of cubs (also did a camp in Jan) in the Oakville area.

John, Jim, Joe and Don covered all aspects of the cub badge requirements including:
- Locating the North Star (for navigation).
- Learn about some of the constellations and some folklore.
- Planets (including the usual talk about why Pluto isn't anymore).
- Meteors and comets.
- Moon phases and how the Moon affects the Earth.
- Basics of how telescopes work.
- And how to use a planisphere/starfinder.

The kids were really good and we all enjoyed ourselves. They had lots of questions and it was clear they learned a lot. A bright and fun bunch.

Our thanks go to their leaders Latif and Jasmine for contacting us and asking for our participation.

The Dunlap Institute for Astronomy and Astrophysics and the Institute for History and Philosophy of Science and Technology are holding a full day symposium about the Transit of Venus which may be of interest to HAA members and those with some astronomy background. It appears to be a fairly comprehensive program, it doesn't seem particularly well suited to someone completely new to astronomy. (However review the program at the link below and see if this will be a good fit for you.) This is a FREE event running on Saturday April 28, 2012 from 10am to 5pm (with breaks).

Doctors Mike Reid, Ralph Chou, James Graham and others will be discussing various aspects associated with the transit. It includes how to view safely, historical events, science learned from transits, how it affects current exo-planet searches and more. It will also include a tour of astronomical instruments on display at the Institute for the History and Philosophy of Science and Technology.

More information, including location and a full schedule of seminars and events can be found:
