Asteroid 1566 Icarus will make a rare close approach to Earth on 15:39 UT 16 June at distance of 0.053 AU. It is brightest between the 17th -19th though. With an estimated diameter of 1 Km it is one of the largest objects to get close to Earth this year.
The asteroid is currently magnitude 14.6, and will brighten to around 13.5. It's distance and slow brightening means there is plenty of time to catch 1566 Icarus.
It is well placed to be visible from the Northern Hemisphere scopes initially, although it will also be visible briefly at astronomical twilight from the SSO scopes when it is brightest.
At magnitude 14.5 -13.5 60 second or shorter exposures may be reasonable, tracking should not be an issue.
Asteroid 1566 Icarus is visible for the rest of the month for northern scopes as it passes from Urda Major to Canes Venatici to Bootes then Virgo.
The asteroid is visible from astronomical twilight until early morning for several weeks.
There is minimal parallax issues with 1566 Icarus, and tracking will work well. The MPC one line ephemeris is
