Last week on Friday 1 June and the first official day of Winter here in

Australia, I decided to attempt a Hubble Space Telescope Solar Transit.

 

The Sun has been very quiet lately, but I did notice over the last week or so there was a possibility of capturing Hubble crossing near a small active region (AR2712).

 

Now Hubble is only about the size of a bus and given it was extremely far away, I was wondering how I might fair this time around capturing the transit at 60 frames per second.

 

Given the Sun is so bright, I couldn't see anything and I always dare not look directly into the Sun, so I used a clock and timing to capture the transit.

 

When I arrived home, I was very excited to see the transit path of a very tiny dot (Hubble) which was traveling at high speed across the the Sun's surface and quite close to AR2712!

Image was captured using Canon Equipment and composited from approximately 80 frames to show the transit path.
