29 January Charts and Sequences Update January 2012

There are over 100 new and revised charts and sequences since the last update in November. Many of these are for stars in the newly formed YSO Section Program, southern stars with new photometry from APASS and campaign targets. The rest are revisions based on issues reported to CHET and requests for new sequences from our observers.

27 January Alert Notice 451: Monitoring of the Symbiotic Variable RT Cru Requested

January 27, 2012: The symbiotic variable RT Cru has brightened in hard x-rays. Dr. Jeno Sokoloski, Columbia University, has requested AAVSO assistance in monitoring RT Cru both now and in the future to see if it is doing anything unusual in the optical. The Swift/BAT hard X-ray light curve shows RT Cru has apparently been gradually brightening over the past few years.  

27 January William Tyler Olcott Mentioned in Norwich Bulletin

The Norwich Bulletin, of Norwich, Ct., published an article about AAVSO co-founder William Tyler Olcott in their blog focused on the history of the town.  It includes interesting tidbits about Mr. Olcott, references to the AAVSO and proposals for ways to commemorate him.

18 January New Tool to Opt Out of E-Mails

16 January The American Meteor Society Also Celebrates 100 Years

The AAVSO is not the only citizen science organization that celebrated its 100th anniversary last year. The American Meteor Society also celebrated it's anniversary. As a token of friendship and appreciation, we sent a certificate mounted on a wooden plaque to Dr. Meisel, Executive Director the AMS. Below is a image of the certificate portion of the plaque. Click for a larger PDF version.

Congrats to the AMS!

11 January New Visual Observing Manual in Chinese

Thanks to the efforts of Cheng Simiao, a young and very enthusiastic observer from Beijing, we now have a new, more up-to-date Chinese version of the "Manual for Visual Observing of Variable Stars" available for download. He wishes that this edition be thought of as a 100th birthday present to the AAVSO as well as an 18th birthday gift to himself.

Congratulations and many thanks to Mr. Cheng!

29 December Light Curve Generator Upgrades

Some work has been done recently to the AAVSO's Light Curve Generator.

Three additional filters, the Tri-R, Tri-G, and Tri-B filters, primarily used in DSLR work, were added to the data that the Light Curve Generator can now display. This should be of great use to people monitoring bright variable stars with cameras, among others.

20 December The AAVSO Computer History Project

Welcome to the AAVSO Computer History Project

 

The purpose of this project is to document the history of the Information Technology Infrastructure of the AAVSO, how it came to be, what hardware was used, who were the people involved, and how the technology was used to further the mission of variable star observing and analysis.

20 December Data Usage Reports are available again

We are happy to announce that after a few months of testing, the AAVSO's Data Usage Reports are now available to all observers again.  You may subscribe to these weekly reports by visiting this page:

06 December New VSP upgrades

We held another VSP workday this week and tackled a few VSP bugs and feature requests. Most of the changes are minor and I'll list them below. We did not get to everything on the list. Our next workday will probably be in a couple of months. Feel free to submit feature requests or bug reports to aavso at aavso.org.

As always, thanks to Michael Koppelman and Chris Watson for taking time out of their day to help us!

05 December Year End Giving

Tis the season
If you’re like many people, you do your major giving toward the end of the year. I think part of the reason is we get caught up in the spirit of the season. The shopping, planning and gift giving is all part of the fun. It feels good. Making a donation to your favorite non-profit organization feels good too.

02 December JAAVSO v39, n2, is published
