| Proposal | I am trying to reproduce the extinction example given in Appendix G of Astronomical Photometry (Henden & Kaitchuck 1982). In the example, this star was observed 12 times through the night at 30-minute intervals. While HR 8641 (omi Peg) is not the star used in the example, it is chosen since it is in Appendix A First Order Extinction Stars and rises, transits, and sets conveniently to cover a wide range of air masses from New Mexico in a single night. As a bright star, it will require short exposures, and it does not have any close neighbors to interfere with the photometry. This will also serve as my first proposal as a new AAVSO member. |

Sorry to have missed this, but the form did not ask for filters. The example given by Henden & Kaitchuck uses U, V, and B.

Suggestion is to use BSM_TX for u' filter and better horizon.

Committed to TX. SU,B,V,R,I filters used. Will run every two days till October 15. Please advise when you have adequate data.
