The dates I entered are off, they should be
March 12, and March 16, based on UTC time.

Committed to BSM_S. What is your intent of this brief time series proposal? Does this time interval cover a transit? 15 images at 60 sec will not cover the entire indicated time interval?

(47927) Michael Paoletti — March 3, 2026, 11:12 p.m.

Ken, it's my first proposal as well as one observing exoplanet transit. So... was concerned about tying up resources for around two hours. If there is a willingness, the UTC time/dates
Start 13:30 -> 15:40 for March 10
Start 10:40 -> 12:50 for March 15
As far as exposures, I really did not know what site was being used nor aperture, QE etc....to calculate that.

I noticed Ic being used, not sure what that translates to. I will research that.
Thank You

Sorry it's the filter!

(4726) Kenneth Menzies — March 4, 2026, 1:17 p.m.

Just explain what you want to do. Let us decide whether we want to approve it or we will provide a reason why not. Do you want to image a full transit? What are you going to do with the images/data?

If so, select appropriate an interval (with some time outside of transit). Just collecting a few images (15), that will not cover that interval, will not provide any useful lightcurve. That would be a waste of time. Identify/select what aavsonet scope will have darkness during that interval (always work in UTC). Note that you now have identified a third different date/time? Which of the three intervals is correct?

Yes, Ic is the filter that you identified in the proposal..

(47927) Michael Paoletti — March 7, 2026, 3:25 a.m.

The intent with this target is primarily to be training exercise, using the captured images in AstroImageJ to plot the measurements. I intend to simultaneously collect data/images at my site and equipment. In near future, observations, once I feel comfortable with my science data, would to import the data to AED.

(4726) Kenneth Menzies — March 7, 2026, 2:54 p.m.

Assume BSM-S. Select a transit that is visible during nighttime there. Select an interval that provides the entire transit plus about 1/2 hour on each end. Request/identify this interval in UTC. Make sense?

(47927) Michael Paoletti — March 7, 2026, 8:12 p.m.

Yes, i do understand. While initially I was looking at sites in the Mid or western US. Looking at BSM-S the +/- 30min ingress regress for both dates should provide full coverage at that site and with the start nearly 2 hrs after sunset ( second date ) and over 4 hrs, at end of observation pre-sunrise ( first date). Even the airmass numbers are great.

(4726) Kenneth Menzies — March 8, 2026, 1:44 p.m.

Would you state the date/time interval once more below in UTC just to make sure I understand them? Select a couple of transits a few days in the future so I have time to get the plan together. The weather may not cooperate.

Target Wasp-43 - RA 10:19:37.96 - DEC -09:48:23.20
Mag ~12.5 - Duration ~ 70 minutes (ingress-egress)
Date: 3-15-2026
Start and end of imaging times which includes (+30min ingress/egrees)
Transit UTC:
2026-03-15 10:39
2026-03-15 12:49

Transit UTC:
2026-03-19 12:16
2026-03-19 14:26

Transit UTC:
2026-03-24 09:25
2026-03-24 11:35

Transit UTC:
2026-04-06 09:48
2026-04-06 11:58

I gave 4 transit dates, pick any or all.
