What does the surface of asteroid 10715 Nagler look like? Asteroid Eros (NEAR Shoemaker mission image above) may have originated in the same Maria group of asteroids as 10715 Nagler. (NASA-JPL)

We’d like to share with you this nice letter Al received from Roger Harvey recently.

Hi Al,

We first met at the Wildacres Retreat, North Carolina mountains, this past April. Despite our lengthy conversation that I will always remember, you never mentioned that you were honored with asteroid 10715 Nagler (1983 RL4).

As luck would have it, my primary effort in amateur astronomy the past 40+ years has been visually identifying asteroids by their position, magnitude, and motion against the background star field.

My observing session for August 16, 2017 happened to include 10715. I saw it at 3:54, 4:32, and 6:28 UT retrograding southwestward in Aquarius at magnitude 16.3. This was ~0.5 magnitude fainter than advertised…not uncommon with higher numbered asteroids. In doing so it was my 5900th asteroid.

My scope is a Lockwood 32” f/4 which (of course!) I couple with your Paracorr Type 1. The 5.5 mm eyepiece yields 676X which is my usual choice. Several times I’ve had to go to 1352X for very faint targets requiring a darker field. Obviously such an effort would be impossible without the excellent optical train above.

Again, it was great speaking with you on the phone today! I am so glad you got a kick out of your asteroid actually being seen by a human (read eyeball, not CCD) (:>). Your joy made my day as well.

Roger Harvey
