HST Campaigns, Planning & Moonlight

The membership database is currently undergoing upgrading/testing. Web functions that involve an interface with the member database (webobs, etc.) may experience intermittent problems. We hope to have this issue resolved within 24 hours (by 5pm Eastern Time on October 1st or 12:00 UT). Thank you for your patience.

I am unable to contribute to the CW Mon campaign visually, because it is impossible to detect 15th magnitude with a full moon nearby, even with my 20" aperture. A similar problem occured a month ago with another campaign target.

Some CCD operators are able, but I think others are also seriously affected by nearby moonlight, especially with smaller instruments and "dirty" atmospheres.

I would like to strongly suggest that the campaign investigators/planners consider the proximity of the moon when scheduling these simultaneous ground based amateur observations!

A good criterion would be to require the moon to be >6 hours in R.A. E or W of the object during the prime observing windows.

Hello Mike


I think that in this case, the time of obervations is governed by supporting HST.
