“There will actually be two windows to spot it. First, between 27 September and 2 October, when it will be visible east just before sunrise, and then again between 12 and 30 October. This is when there will be a better chance to see it, if you look to the west just after sunset.”

So in other words, don’t bother looking next few days, it’s lost in glare of the Sun and will be re-appearing after sunset in western skies, on evenings of Oct 12-20. After Oct 20 I presume it will be too faint to see easily as it heads back into deep space.
