Discovery Challenge for Astronomy Day 2018

Congratulations to Carl Bandura who correctly identified the galaxy as NGC  4564 – an 11th magnitude elliptical galaxy located about 57 million light-years away. NGC 4564 crossed the meridian at 22:25 PDT on May 12th but it is still a bit light then at this time of year so waiting another hour is a better time to observe it.

Our Observing Director, Robert Conrad,  and I have teamed up to bring you an observing challenge in preparation for Astronomy Day. You can win a prize too and if you need hints,  we will provide a hint each day for the next few days. See all the details below. Good luck!
Checkout the latest hints – all the hints have now been provided!  
Remember to send your answers  to [email protected]m or [email protected]com before 2pm tomorrow (Saturday May 12th) to be eligible to win a special edition of “Atlas of the Stars”. We will be having a draw following Robert’s 2-3pm presentation in Simon Fraser University’s Academic Quadrangle room AQ3150 during Astronomy Day/Science Rendezvous – we hope to see you there.
Discovery Challenge
Here is new challenge for you that will test your Stellarium charting abilities and ties in with Astronomy Day and Science Rendezvous at SFU on May 12th, 2018 (more info at  http://rasc-vancouver.com/2018/04/28/science-rendezvous-and-astronomy-day-2018/).
The image below includes at least  15 galaxies but can you identify the galaxy in the yellow circle and when would be an good time observe it on Astronomy Day (May 12th, 2018)?
You can get help in tackling this challenge by attending Robert’s presentation on using using Stellarium and locating objects at Astronomy Day. Additional clues will follow in the next few days.  Send your answers to [email protected]com or [email protected]vancouver.com.  Participants who correctly identify the the galaxy will be eligible to win a special edition of “Atlas of the Stars”, published every 10 years, in a draw following Robert’s 2-3pm presentation on Astronomy Day.

Hints (two more coming in the next few days)
  1. The field of view in the image is approximately 3.4 by 2.3 degrees and the same field is visible during most of the night on May 12th from Vancouver. That is not much to go on but look for further hints over the next few days.
  2. Asteroid Kalliope (magnitude 11) passes through the bottom left hand side of this field from May 3rd to May 12th, 2018.
  3. The image includes parts of the Virgo Galaxy cluster.
  4. The final hint is that the image contains several Messier objects including M58, M59, M60, M87, M89.
