Wed, 13 Sep 2006 - Comet 2006 M4 (SWAN)

Whilst comet 2006 M4 (SWAN) is still at a small solar elongation, this is increasing rapidly. It should emerge from conjunction for Northern Hemisphere visual observers in mid September. SPA members in Scotland are at the optimum latitude to make a visual recovery, around September 13. The comet is due to reach perihelion in late September and could reach 6th magnitude in October.

Although it is initially a morning object it should be visible in the evening sky by the end of September, however moonlight will begin to interfere. It is currently in Leo and tracks north eastward, reaching Canes Venatici in early October. An ephemeris is available here, and updates will appear as they become available.

Please report observations directly to me, as they may be missed if posted on discussion forum pages.
