Comet K2 Panstarrs is expected to remain a reasonably bright binocular object as it leaves Ophiuchus and passes into Scorpius as it continues it’s southward journey.
From AAVOS August Variable: Variable star R Aquilae. Located just off the trailing edge of the western wing of Aquila the Eagle, about 5 degrees south of Zeta Aquilae, which marks the wing tip. R Aquilae is a red giant star and about the same mass as our Sun, but, like many of us, has expanded as it aged. If it were located in place of our Sun, Earth would be orbiting inside its outer atmosphere!
At its brightest, R Aquilae is visible to the naked eye as a dim, red star but it dims over 600 times from its brightest making it just visible in binoculars. Its period from one dimming to the next is 270 days. Oddly, the period has been decreasing about 9 hours per year since it was discovered to be variable in 1915. The reason for this decrease is unknown at this time.
