The nova is best seen from the SSO observatories from around astronomical twilight in the evening, when it is 30 degrees above the horizon, and for about half an hour more. The nova is imageable from the northern hemisphere scopes at astronomical twilight (24 degrees above the horizon). The nova should be reasonably recognisable in a field of relatively dimmer stars, not far from globular cluster Djorg 2.
This is the third bright nova reported in Sagittarius. It is currently around magnitude 9 and may possibly brighten further.
