What I Did On My Spring Break

SXN
By SXN - May 21, 2013 - 7:42pm

Last year, during my trip to the southwest and California to relocate AAVSOnet assets from Tom Krajci’s residence, I stayed with Tom Smith and his wife Donna for two nights. We talked at some length about the status of the Morgan 24” telescope and what it would take to get it commissioned and taking data. It seemed to me that there were several phases of the commissioning process that were going to require extra hands, eyes, muscles and brains for Tom to get them done. I told him I would be happy to come spend a week with him in the spring to help with some of the physical plant work as long as Arne approved the related travel expenses.

In January we began to make plans and set up an itinerary for my trip to New Mexico to help Tom work on the telescope and shelter.  Continue Reading

Herb Luft's notebooks: new science from the AAVSO Archives

Matthew Templeton
By Matthew Templeton - May 10, 2013 - 12:25pm

The AAVSO Solar section and AAVSO headquarters are hosting a special guest this week and next, Leif Svalgaard (at center in this photo) of Stanford University/Solar Dynamics Observatory.  Leif is here to digitize sunspot records from the original notebooks of AAVSO member Herbert A. Luft (1908-1988), housed in the Thomas R. and Anna Fay Williams Archives. Continue Reading

Charts and Sequences Team On A Mission

SXN
By SXN - April 8, 2013 - 3:23pm

Compared to the pace of even five years ago, the speed at which the charts and sequences team addresses new and revised sequences is simply astonishing. One of the important factors in this NASCAR paced activity is APASS, the all sky survey nearing completion. Every time a data release is made available the team re-examines its lists of requests and reports to see what else can be fixed or created anew in light of the latest photometric data available.

DSLR Workshop Wrap-Up

SXN
By SXN - March 30, 2013 - 10:44am

It is amazing what two-dozen people can get done in a weekend if they are organized, serious and willing to put in the time and effort to make the most of a two and a half day workshop. I opened up the Google Drive page containing all the final drafts of six chapters written at the workshop and edited during this past week and the material is shaping up into what I believe will be a very useful introduction and instruction manual for newcomers to DSLR photometry.
