GRB 090510 is the only LAT-detected sGRB with a measured redshift (z = 0.903, Ackermann et al. 2010). We compare it here to LAT observations of GW150914. The 100 MeV–10 GeV lightcurve of GRB 090510 has been scaled to z=0.09, the redshift corresponding to the best-fit distance from the GW
observation (Abbott et al. 2016). The red arrow indicates the 95% confidence upper limit measured during
T1 across the LIGO localization region and is similar to the upper limits from the measured lightcurve. Even
though GRB 090510 had exceptionally bright prompt and afterglow emission, this figure demonstrates that
the LAT would detect transients more than an order of magnitude fainter than GRB 090510, provided a more
favorable placement of the GW candidate so that it enters the LAT FoV within 100 s of the trigger time.

What's the ideal bike for gravel riding? We may be biased but the Rodeo Labs Flaanimal platform will reliably carry us along the varying terrain, with comfort improved by Redshift components (stem, seatpost, bars), and traction provided by WTB tires, sealant. We have Byway, Raddlers and Ventures of varying sizes (mm and wheel size)
The ideal bike is the one you have, and on a PTGT trip, its our highly capable Flaanimal.
We’re so stoked on all of our partners as they are on the point end of design and innovation. The whole is greater than the sum of the parts, and the synergy between our partners has created the best gravel bike fleet ever.

It's been more than a decade since we've worked with Red Shift Theatre. Today, their Jonathan Holloway and Emma Rees popped in to see Michael and spotted their Nosferatu poster on our wall.

SN 2024iss
Type II supernova
Galaxy: LEDA 1846725 with redshift (z) of 0.0033.
Position: 12h59m06.15s, +28d48m42.7s
Discovery date: May 12, 2024
Discovery group: GOTO
Constellation: Coma Berenices
TNS: www.wis-tns.org/object/2024iss
Image data

Comparison stars from APASS DR10.
LEDA 1846725 lies in the direction of the Coma Berenices Galaxy Cluster Abell 1656. In fact, one of its many designations has the Abell name as part of it: ABELL 1656:[GMP83] 3744. However, per the NED the redshift for Abell 1656 is z = 0.0233 which would place the cluster some 7 times farther than the host galaxy for SN 2024iss. It could be that the redshift for the host galaxy has a huge cluster motion, but that would be the equivalent about 6,000 km/s towards us relative to the center of the cluster.
The AAVSO has SN 2024iss in its database. Though there are gaps in the data (as of this moment), SN 2024iss may have peaked about magnitude 13.2V around May 31, 2024.
The distance to Abell 1656 has quite a scatter, but assume it is about 100 Mpc or about 330 million light-years. If the host for SN 2024iss is at that distance that would mean this supernova is a superluminous event with an absolute magnitude of about -21.8! However, if the host galaxy is in the foreground with little extraneous motion other than the cosmological component (i.e. due to the expansion of the universe), that would put the galaxy only 13.8 Mpc or about 45 million light-years distant. That would reduce the absolute magnitude to about -17.5. A typical Type II supernova peaks around -17.0. (Note: a Hubble Constant of 72 km/s/Mpc was used for the calculations).
