Details:
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!
