2009.09.09

Note: I'm writing a Second Edition of the book Exoplanet Observing for Amateurs, and it will have much new material. Some of the new material is prompted by silly notions coming from the AAVSO community of observers, who don't understand that "exoplanets are not variable stars" as explained at: http://brucegary.net/AXA/NotAAVSO.htm  AAVSO observers have much to unlearn if they are to become good exoplanet observers!

Updated web page "dataformat.htm" (linked to from the AXA home page, also found here: http://brucegary.net/AXA/dataformat.htm  It explains the 3 ways to process images that can lead to a data file submitted to AXA (2 of them are common for AAVSO observers). 

Uploaded spreadsheet LCep.xls to same web site http://brucegary.net/book_EOA/xls.htm. It's to be used with CSV-files created using ensemble or comp/chk photometry. It can also be used with AXA data submission files. Lot's of instructions included. 

Replaced spreadsheet LCx_template.xls with LCas.xls at http://brucegary.net/book_EOA/xls.htm (new version has lots of instructions; only for use with CSV-files created using an "artificial star" as reference & nearby stars as "chk" for possible use in spreadsheet as reference).

I've decided that it's feasible for me to update plots when submission rate has slowed & I have time. Updates therefore cannot be counted on to be current since I won't be doing it after each data submission. This is a compromise between what we'd all like and what I'm able to do.

HAT-P-2 correction! Lubos Brat pointed out that the HJDo listed on the AXA home page (taken from Schneider's Extrasolar Planets Encyclopaedia) is discrepant with the discovery paper value and since the ETD has an observation that is consistent with the discovery paper HJDo, and since the single observation in the AXA can be viewed as OOT, the correct HJDo must be that given in the discovery paper by Bakos et al, 2007. I agree with this interpretation and have amended the AXA home page HJDo listing. Thank you Lubos Brat for notifying the AXA about this discrepancy.

20090322 of HD 68988 (R) by Ramon Naves (Spain). This is close to a confirmation of Hentunen's Feb 25 transit. Depths agree but mid-transit times (inferred from assumed length) differ by ~4.1 hrs for events 4 periods apart. High priority for future predicted transits.

A web page has been created for downloading raw images for practicing image analysis and spreadsheet processing skills: PracticeImages 
Update on WASP-12: The lead author on the discovery paper, L. Hebb, has confirmed that a typo was present in the arXiv paper and the correct HJDo is 4508.9761. (By coincidence, 4506.7961 would work just about as well.) The BTE_ephem.xls has been updated (downloadable at http://brucegary.net/book_EOA/xls.htm).
20090101 WASP-12 (C) by Veli-Pekka Hentunen and Makku Nissinen (Finland) at 03:12 UT, 2009.01.05
20090104 WASP-12 (C) by Veli-Pekka Hentunen and Makku Nissinen (Finland) at 03:12 UT, 2009.01.05
Since Jan 1 was a "no show" and Jan 4 was observed to occur, the reported HJDo in the discovery paper (and included on Schneider's Extrasolar Planets Encyclopaedia) must be in error. The simplest explanation is that a misprint is present in the discovery paper because the survey HJD is correct but the stated HJD for high quality LCs is off by ~265 minutes. Perhaps two numbers were transposed, so that HJDo of 4506.9761 should be 4506.7961. This explanation is consistent with the Hentunen and Nissinen observations.

Corrected small errors in TTV ephemeris solutions for XO-2, TrES-2, XO-3, WASP-1, HD 189733, GJ 436 and CoRoT-1.
Added web page for new BTE WASP-12 & listed in AXA home page.

20081106 CoRoT-1 (C) by Hentunen (Finland)
Decided, finally, to extend the V-mag criterion for BTE to 14.0 (from 13.0). This means that at this time 3 more BTEs will be added (all CoRoT). Hentunen's LC convinced me that amateurs are capable of making scientifically useful contributions for these fainter BTEs.

2008.12.02

Corrected an error on the HD 17156 web page. There was a one day error for the mid-transit HJD for Vanmunster's 2008.05.11 observation. This observation is still a mystery since it occurs 11 days after the previous "b" trnaist and 10 days before the following "b" transit.

20080806 HD 189733 (C) by Petr Svoboda (Czech Republic) using a 1.33-inch aperture camera lens "telescope." 
    So far this is the smallest aperture (that has come to my attention) used to produce a scientifically useful exoplanet transit light curve.
    Petr Svoboda tentatively holds the record for an informal contest to demonstrate that "aperture isn't everything!" Congratulations Petr Svoboda of the Czech Republic!

20081102 CoRoT-2 (C) by Gary (Arizona). The shortness of this LC (0.8 hr) breaks all my rules, yet it seems to contribute something useful.

20081026 XO-4 (C) by Srdoc (Croatia) using a 2.5-inch telescope! Congratulations Gregor, this is one of the smallest apertures used for a successful measurement of any exoplanet transit.
    And this transit depth is only ~9.5 mmag. This could become a bragging rights contest, and I invite a competition.
